Time/Date to GMT keeping in mind DST

I have a servlet that gets the system Time/Date and needs to convert it to GMT(Greenwich Mean Time), it also needs to convert for DST(Daylight Savings Time) in the code. Any help would be greatly appreciated.

Presumably the current time zone of the client is not GMT/UMT.
So you need to create a TimeZone for GMT/UMT.
Then you use that when creating SimpleDateFormat. Then the format method of that instance will produce a string with the correct (relative) time value.

Oracle SQL HELP with convert GMT to EST and DST and Date offset

Hi, I have a query that does not seem to work trying to convert a date field that is in GMT to est and using extract(timezone_hour FROM TO_TIMESTAMP_TZ as an offsetr
HEre is my sql
dtl.start_dt_gmt + (extract(timezone_hour FROM TO_TIMESTAMP_TZ( dtl.start_dt_gmt,'DD-MON-YYYY HH24:MI:SS TZH:TZM'))/24 ) START_DT_Local
If the date (dtl.start_dt_gmt) is may 1 and gmt starts at 04:00 AM , the extract offset produces -4
However, if the date (dtl.start_dt_gmt) is Feb 1 which begins at 05:00 AM GMT, the date offset still gives 04. What am i doing wrong? Any help would be appreciated. Thanks.

If your data is not associated with timezone then you'll have to use something like
case when dt between A and B then dt-1/24 else dt end; <-- This will give you 1 hour back of EDT. So, as far as concern at database level, it is nothing to do at db level, because db is used by application, so you need to code in the app.
Oracle never actually changes a TIMEZONE column value when you set your system to be on daylight savings time. There are several built-in DST DATE conversion functions for changing to daylight savings time:
current_date
current_timestamp
localtimestamp
dbtimezone
sessiontimezone
extract
from_tz
to_timestamp
to_timestamp_tz
to_yminterval tz_offset

HELP - How to Convert Date in GMT to Local time in Applet

Hi All
Is there a way to convert a date from GMT format into a local time say IST in my Java applet, this GMT date is coming from a postgresql database.
Thanks in advance
Swaraj

Try this with your customization:
java.text.SimpleDateFormat format0 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
java.text.SimpleDateFormat format1 = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
java.util.Calendar cal0 = Calendar.getInstance(new SimpleTimeZone(0, "GMT"));
java.util.Calendar cal1 = Calendar.getInstance(new SimpleTimeZone((int)(5.5*60*60*1000), "IST"));
format0.setCalendar(cal0);
format1.setCalendar(cal1);
java.util.Date date = format0.parse("2003-01-25 00:15:30");
java.lang.String formatted = format1.format(date);
System.out.println(formatted);

Getting today's date in GMT time zone

Hi,
I have a simple question, but am confused how to do it:
I need the current GMT date (as a Date object) ..how do I do it?
Date date = new Date();
This returns the current date but according to the timezone of the system time & not GMT.
Using SimpleDateFormat comes close but it returns as a String object:
SimpleDateFormat dateFormat = new SimpleDateFormat("some format");
dateFormat.setTimeZone(new SimpleTimeZone(0, "GMT"));
Date date = new Date();
String dateAsString = dateFormat.format(date);
This gets the current GMT date but as a String object, but I want it as a Date object.
Can you please throw some light on this? I guess there should be simple way to do it or am overlooking something.
Thanks!

I don't think Calendar is useful here.
"Current date as GMT" is meaningless. Current date (and time) is just "now." Timezone is not part of the picture. If you want to present the current date/time in GMT, then....
Date date = new Date();
DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm z");
System.out.println(df.format(date));
df.setTimeZone(TimeZone.getTimeZone("GMT"));
System.out.println(df.format(date));

I keep losing the time date stamp when uploading the video and need to keep it HELP

Using Premier 7 making a video for my son and need to keep the time/date stamp that is visible when playing the video direct from the camera to the tv. When I compile the video and burn to DVD this Stamp disappears how do keep it on the film that I am editing so when I burn it will be still there?

Ah, PrElements 7. I thought that you had Pr 7.0, which was also named PrPro 1.0.
The forum that you want is HERE.
Now, in PrE's forum, look for the FAQ section, to the right of the main page. Steve Grisetti has done a few FAQ's on HDD cameras, and their MPEG files.
As for your Date/Time stamp, I am not sure if any of the DVDate programs will work directly with that. There are a few threads, but I do not recall the solutions. Do a search of that forum and you will get some info.
Back in later versions of PrPro, I have some tips on TimeCode, but that is different than what you want.
I also do not know if something like SceneAlyzer Live can Capture what you want.
Still, others have asked in the PrE forum, so there might be some solutions.
See you there,

Time & Date keep refreshing in BIOS

Sorry
I'm new to Toshs so I am sure this is a very easy problem. Keep re-setting the time & date.
It will hold in the BIOS for about a week and then need to be updated again. I'm upgrading the hard drive anyway but don't want to start this without getting to the route of this issus.
Battery issue?

Sounds so
I think the RTC (BIOS) battery is not fully charged.
In the user manual you should find details about BIOS battery and how long its necessary to charge it.
I think you should let the notebook running for about 12-16 hours on ac adapter.
Then the RTC battery should be fully charged
Bye

Time/date keep changing

In the past few days, my Iphone has been changing from current date/time (January 30 at various times) back to January 1st or 3rd and not the correct time. Is anyone else having this happen?

We have 4 iPhones in the house and they're all experiencing this problem at random. I spoke with an AT&T CSR and she had me do the usual trouble shooting steps but nothing helped. She transferred me to a "Network Technician" who checked the network and said there was "definitely" no problem on AT&T's end and that I needed to call Apple. He may be right since not all of the iPhones in the house experience the problem at the same time. Sometimes, like today, only 1 of the 4 is experiencing the time date problem. We've seen the problem on 3.1.2 and 3.1.3. The phone experiencing it began showing the right time & date before I could call Apple.

Things to keep in mind while finalizing To Be Process

Hi Gurus,
Please tell me, what things i should keep in mind while finalizing to be process?
And what to do when client ask for something which i dont know that SAP is providing or not?
Waiting for reply.
Thank You
Regards,

hello please read below
points will be appreciated
Implementing a package can be a traumatic affair for both the customer and the vendor.   Get it wrong and the vendor may get paid late or have to resort to lawyers to get paid and tarnish their reputation.   For the company the new package may not work the way they expected, be late or cost a more than budgeted for and take management will take their eye off running their business.
Recently a client asked me what I would consider to be the five most important things one should consider before embarking on an implementation.   This isn't a simple question, although there are many factors to think about after some consideration for me the top five are way ahead of the others.
My top five factors to consider would be:
1. Set up a Project Board,
2. Secure the resources,
3. Complete the GAP Analysis,
4. Have detailed Cut Over Plans,
5. Train the users.
Taking each one in turn:
The Project Board
The correct set up and operation of the Project Board in my view is major factor in the success failure of the project.   The Project Board will consist of the stakeholders, key users and the vendor.   The Project Board is part of the governance of the project.   The Project Board will meet regularly to ensure that the project plans are created and being executed as planned, moves from stage to stage with all the deliverables being signed off is resourced properly.
The Resources
Three types of resources are absolutely necessary -- end users, change team and technicians.
Early involvement by the end users is absolutely necessary, as they will be the ones living with the system for hopefully many years to come.   They will want to feel involved in its implementation.   Buy in from the end users of the system is absolutely essential if the system is to have a long and stable life in any organisation.
The Change Team will identify the gaps between the package and the business requirements, re-engineer some of the businesses process to cope with the package, train the users to ensure implementation is smooth as possible into the business.
The Technical Team will prepare the systems environment for the package, apply any software fixes from the vendor, implement the software in the best way possible for the organisation set up and tune the software for the particular technical environment.
GAP Analysis
A through gap analysis will identify the gaps between how the business operates ad its needs against what the package can can't do.   For each gap there will be one of three outcomes which must be recorded and actioned, GAP must be closed and customised software can be developed close the gap, GAP must be closed but software cannot be written therefore a workaround is required, GAP does not need to be closed.
In simple terms: Gap means small cracks. In SAP world. In information technology, gap analysis is the study of the differences between two different information systems or applications( ex; existing system or legacy system with Client and new is SAP), often for the purpose of determining how to get from one state to a new state. A gap is sometimes spoken of as "the space between where we are and where we want to be." Gap analysis is undertaken as a means of bridging that space.
Actual gap analysis is time consuming and it plays vital role in blue print stage.
Cut Over Plans
Detailed plans need to be developed for cutting over from the old system(s) to the new.   Parallel runs of what will happen over the conversion period using test data, convert and watch for a period after wards to ensure nothing unexpected happens.
Train Users
Well trained users will support and defend the system on site. Unsupportive users will continually undermine the system and eventually it will be replaced.   Therefore the more effort you put into helping the users master the system early the better.
Difference between the User Exit & Gap analysis.
Both are quiet a different and has a small relation.
User exits are standard gate ways provided by SAP to exit the standard code and we can write our own code with the help of ABAP workbench.   its not new functionality which we are trying to build in sap but its slight enhancement within the same code.
Gap analysis is start point of Realization and once blue print is finished we have to find the realization of sap system for client requirment and there will be certain gaps when compared to system fit. Those gaps can be closed either by re-engineering of business process to fit with SAP or we have to use USER exits in case of small deviations or complete enhancements with the help of ABAP to fit with the SAP system.   *-- V.

More Image Time/Date Questions

I hate to keep bringing up Time/Date/Time Zone related issues, but it seems I have another...
I have certain images for which I have changed the date and time and time zone. The metadata reflects the proper time, date and time zone, but oddly, when I filter the images based on "Capture Day of Month" I get results that cause me problems.
For example, I have an image that was shot on 1/15/2007 at 2:14 AM GMT + 7:00. This is what the Metadata tells me. When I go to Metadata -> Adjust Date and Time, it tells me that the Original was shot on 1/14/2007 at 2:14 PM. (It doesn't tell me the Time Zone of the original here).
When I do a search in this project for all images shot on the 15th day of the month, this image does not show up in my results. The metadata says 1/15, but the original says 1/14. This is an issue for filtering purposes and leaves me wondering how many images get left out of my filters when I apply them.
This could be an odd case because I might not have managed the time/date/time zone properly on import. I did try to change them to the correct time/date/time zone after the fact and thought all was good until now.
Does anyone know how I can rectify this situation? I just want to make sure that the time/date/time zone of all of my images is correct.

Nathan,
I just got back from some travels. I just checked again and it seems to now be working. It really is the strangest thing. Basically, I checked it both ways. I went into a project that had images from multiple days (I now want to separate my images into projects by the day they were shot on). I picked two filter scenarios: 1) "Date", where I specified, "Capture Day of Month" "is" and I typed "15" and 2) "EXIF", where I specified, "Capture Day of Month" "is" and I typed "15". It did not work when I had all of the images lumped into one project. I subsequently manually sorted my images by looking at the date of each one before moving them into their new respective projects. Now that they are in their own projects, it seems to working.
Aperture has a long way to go to make time management simple and accurate. There are a lot of things going on (where the image was shot, what the camera time was set to, which time zone the computer is in when you import the images, how the time settings on the computer are configured, etc, etc...). It really is a lot to manage. Thankfully, Aperture allows you to correct these issues, but it doesn't make the task simple nor straightforward.
Perhaps it is a camera issue and not a software issue? Maybe camera manufacturers need to make their products more like our phones, where the time is registered automatically based on your GPS location. I am not sure if GPS enabled cameras have this capability. The computer should be able to recognize this GPS stamped time and embed the data directly into the image. Science fiction? Perhaps.
There are far too many obstacles that get in the way and mistakes are easily made along the way. As mentioned, Aperture allows you to correct these "mishaps", but not with the type of ease you would hope for. Unless you shoot and upload all of your images in your own time zone and have your camera clock and computer clock synced and set correctly, you are bound to have inaccuracies along the way. This is a shame for those who try to manage this stuff down to the "T".
Sorry for my rant as I have digressed from the topic at hand.
I have begun to import my images under a system mentioned by another user in a different thread (I will have to go back to find his alias). I basically set my camera to UTC time and then upon import set the actual time to the time zone that I shot the images in. This saves me from having to reset my camera every time I change time zones and from also having to adjust it during daylight savings time.
This alone seems to have solved my issues for now and going forward. I still run into issues upon import though from time to time that are perplexing as they are frustrating. For example, I just got back from Houston, Texas. I live on the East Coast. The first issue I had is that the import dialogue box doesn't tell you the "Adjusted Date and Time" correctly (or so it seems to me). After importing the images, the date and time is correct, but this is not reflected during import, nor communicated in the import dialogue which always confuses the heck out of me.
I blame part of this on the fact that Aperture is probably seeing the original in UTC time. It is then correcting it based on the time zone that I chose (CST), only I am importing in EST. It all adds up to a bunch of confusion. Even after trying to decipher it all and by doing the math, I still don't think it adds up correctly in the import dialogue. When I make adjustments to the time, date and zone during import, the data always looks incorrect in the import dialogue. This I have tested over and over again. I would be surprised if I am the only one who notices this. I can't figure out why it happens. The good news is that the actual images do have the correct date, time and time zone after import, but this anomaly still makes it confusing during import.
The second thing I am noticing is that these images, which do show up correct, don't always import correctly when you auto-split your projects into days. For instance, if the original image (UTC time) was on the 15th, but the corrected image ends up on the 14th, that image doesn't get sorted with the other images that were shot on the 14th (even though this image was shot on the 14th in the time zone you shot it. This is obviously the time and date you want associated with the image). This again makes importing a pain in the you know what and very confusing.
A third thing I've noticed is that there is no way to check only the images for a certain day. You have to uncheck everything and then check (individually) each image from a given day. This is not a good system nor workflow. In order to avoid it, you have to import everything at once and then separate your images into projects later. This also isn't a good system for obvious reasons.
I don't mean to turn this thread into a "What's wrong with Aperture import" discussion. Most of what I am describing would probably be better served as part of a feedback request to the Aperture team. I will certainly get to that as well.
There is another confusing thing to me though based on the original part of this discussion thread. The image that I was originally describing - the one where I shot it on 01/15/07 at 2:14 AM GMT +7:00 (which shows up as originally being shot on 01/14/07 at 2:14 PM (I get this by going to "Metadata" -> "Adjust Date and Time". The thing I don't understand is why the original even says that. When I adjust images, I always apply those adjustments to the Master. How do I actually get this to reflect, as it seems that it is still being read with an original time as the incorrect time and date? Also, why - upon making a time and date adjustment - does Aperture tell you that this action cannot be undone? It seems you can make as many changes as you want, and even changed the images back to the original time and date.
Anyway, that's it for now. I hope I haven't confused you with this lengthy discourse.

How to count occurences of a certain string in incoming real-time data? Also displaying RTC data. Current VI included

I use LabView student Express 7 on a Windows XP system.
Time-frame: we are doing final integrations for our balloon experiment today. We just got told that the press wants to view real-time data, which we haven't programmed for. I need help to get a working VI at the latest by 25.02.2004 before 0800(morning) (GMT+1).
Note on license
It is a student balloon flight, and the data will not be used in scientific work, so the I am not breaking any license agreements (I hope).
Problem synopsis:
The balloon continually transmits data at 9600baud. The data is a semi-repeating header followed by a constant lenght data-package arranged like this:
BEXUS[h][m][s]BEXUS[h][m][s]
[Raw binary data, 7channels*8sub-channels*8bits]
What the groundstation is doing right now:
Take all incomming data and save (append) the data to a file without any data-handling. (We figured we would go post-processing).
What I need to change in less than 24 hours:
- Add a "package" counter
- Add a display of the clock data (RTC)
How I planned to implement the changes:
-RTC display:
The RTC data is in BCD format, since that means that if you look at the data as hex numbers, you get the hours and minutes and seconds out in "clear text". That is 12 hours is 0x12hex. I figured that I can do a match pattern BEXUS and pass the "after substring" to another match pattern BEXUS from which I feed the "before substring" to a type-cast VI (casting string to u8) and displaying that, which should give me a display of "123000" for the time 12:30:00... I couldn't get it to work at all when I tried out the supplied "beta" vi.
- Package counter:
Counting how many BEXUS that gets detected and dividing by 2. I don't know how to do this. I've looked on the forum (a good thread on the problem: "how do I count the number of *'s in a string") but these use either loops or arrays... and I'm not sure how this works when I'm getting the data in at realtime. I cant make an array and then count it, since then the array would grow fast and possibly interfere with saving of the data??? Saving the data is critical.. without that file we cant do post-processing.
Since my time is so limited (I'm not even supposed to do the groundstation software but they called on me in the last minute because no-one else had time/wanted too/could do it) I hope that you could make an exception and provide me with working VI's (based on the one I have attached) so that I can show something to the press! (Free comercial for NI!! Since the student version shows the National Instruments water-mark on all VI's!!! Possible TV time!!)
Thanks!
PS: even if you are to late (after 25) post anyway!
Why:
-I can learn from it
-the launch might be delayed due to weather conditions
-others might find it amusing!
Thanks again!

I have a valid example data file attached to this thread.
If you open BEXTEST.bin in a hex-editor of your choice, you'll see the BEXUS as 42 45 58 55 53 and then the time as 00 28 09 etc.
I couldn't get Joe Guo's VI to work. It doesn't count packages correctly, and the time is not displayed correctly either.
The file was saved using a straight save to file VI.
The data is from actual launching area tests performed a few mintues ago. The time displayed is "On time" e.g. how long the gondola has been powered up.
I have a spare T-junction, so I can hook into the balloon real-time data as we fly, in case anyone care to see if they can figure out why the latest version of Joe Guo's program is not displaying correctly.
I will monitor this
thread during and after flight to see if anyone can make it in time!
Thanks for the great effort!!

Does anyone know of a VI or how to go about writing one that will prevent the computers time/date from being disabled while an application is running.

Does anyone know of a VI or how to go about writing one that will prevent the computers clock/time from being disabled while an application is running. The time and date can normally be reset while an application is running by clicking on the time/date in the lower right-hand corner of the computer screen. I have an application that runs over several days and it is critical that the time and date of the computer not be changed. Is there an easy way to lock this out from the user? Note that I am what I consider an advanced beginner in LV.
Thank you,
Chuck
Solved!
Go to Solution.

That is not something you can do from LabVIEW, as it is an operating system operation, and it will depend on the operating system that you're using. On Windows you can use a group policy to control this. Please Google on "prevent time and date change in windows".
Also, please try to refrain from stuffing your entire message in the subject block. Keep the subject short, but descriptive enough so it can be understood what you are basically asking. Thanks.
