How to detect Summer Time change (GMT or GMT+1)

Hi all,
My problem is that I retrieve from xml a timestamp. It indicates the London local hour.
I do format the Calendar constructed object with SimpleDateFormat, but I have to append "GMT" or "GMT+1" (BST) to the output String.
How do I detect when the time is BST (British Summer Time) and when Greenwich Mean Time?
Thanks for your help.
Best regards,
Antonio

Hello Jarrod
Thank you for your help, I looked the previous threads and download .NET Framework 2.0. Finally I am able to get it work.

java.sql.Timestamp does not have an explicit timezone. To quote the Javadoc, it is just "a thing wrapper round java.util.Date" Yup.
It has an implied timezone of UTC (same as GMT) and cannot be changed. I say again - it cannot be changed.I disagree. Though the definition is "millis since 1/1/1970 00:00:00.000 UTC", there's nothing in the object to reflect that it's 1/1/70 00:00 or that it's UTC. If the definition were changed tomorrow to "millis since 12/31/1969 16:00:00.000 PST", the class would not change at all. I wouldn't say that the identical class has an "implied TZ" of PST vs. UTC just by that change.
So while it's defined relative to a time in UTC, there's no TZ--implied or otherwise--that's part of the object.There is no field in Timestamp or Date that hold a Timezone so neither has an explicit* Timezone. The timezone is implied by the long value it holds being the defined as being the number of milliseconds since 1/1/1970 UTC. Of course this is only by convention. One can insert any long value one wants in it and say that this is the offset since any arbitrary epoch in arbitrary units in an arbitrary timezone but then non of the helper classes such as SimpleDateFormat would function correctly since they interpret the long value as being milliseconds relative to 1/1/1970 UTC.
Of course if you were really really bored and really felt like doing something pointless you could re-define the units for the long value and define your own epoch and write your own Date helper classes.

Yeah, I'm having a hard time focusing on work now, and felt a little pointless ballsniffing pedantry would be refreshing. :-):-) I suggest a couple of strong cups of Typhoo (If someone hasn't already done so, maybe I should create a JTyphoo API). Much better for you than Java.

Odd clock drift since summer time clock change

This is a weird one. Since the clocks changed back for daylight savings time (here in the UK, on Sunday morning from BST to GMT) I've been getting a strange error: while I'm editing a file in vi(1), occasionally when I come to save it tells me the file has changed on disk (it hasn't).
I thought I was going mad until a colleague said he's seen the same warnings on his machine in Eclipse. It seems to me like the clock is constantly drifting/being adjusted - I'm syncing with NTP to time.euro.apple.com, and I am seeing a lot of NTP updates in the logs:
system.log:Nov 2 19:18:26 mightymac ntpd[34353]: time reset +0.280424 s
system.log:Nov 2 20:26:10 mightymac ntpd[34353]: time reset -0.857206 s
system.log:Nov 2 20:26:10 mightymac ntpd[34353]: frequency error -589 PPM exceeds tolerance 500 PPM
system.log:Nov 2 21:01:15 mightymac ntpd[34353]: time reset +0.974976 s

system.log:Nov 3 10:07:17 mightymac ntpd[34353]: time reset +0.491741 s
These are big jumps - a second, half a second, much more than I'd expect to see. Given it's happening on a colleagues machine we can rule out my clock battery or other local hardware/software issues, it's happening both when I'm at work and at home (on two different networks), and it's only happening since the summer time change on Sunday.
Has anyone else seen this? This is on 10.6.4, on two machines that have not been rebooted since the clocks changed.

I have a similar problem - when I start up my clock has advanced about 13 hours. It seems to have been doing this since daylight savings changed. It has the right time zone and I have unlinked synchronisation but it keeps happening even when it is locked.

Convert Local Date and Time into GMT

In Oracle how to convert date & time in GMT. Suppose the input will be local date & time e.g. ‘IN’, ‘15/11/2010 15:20:30’ ( country Code, DD/MM/YYYY Hr:Min:Sec in 24hr format) output should be in GMT format.

I don't think this should be in the OLAP subforum. At least try to look for the correct section before posting next time.
Apart from that, you can try a combination of the From_Tz and Tz_Offset functions.

6300 - Changing Time Zone (GMT+1) Changes All Cale...

I have a 6300 and a calendar full of important meetings and so on.
Last weekend we went on to GMT+1 hour (British Summer Time).
Changing the time settings in the phone to "GMT+1" changes all the calendar times to +1 hour as well.
Why does the phone do this (is this dumb or what !) ?
How can I get the phone NOT to change the calendar times whilst changing the time of day ?
Good wishes to all.
Simon
Solved!
Go to Solution.

Google calendar has resolved this problem for me by allowing Time Zone entries for Calendar items.
1. I now enter calendar entries with the local time in my Google Travel calendar.
2. I then duplicate the entry in my Google personal calendar and edit this entry to identify the destination Time Zone.
3. I then allow Google calendar to update my Outlook calendar. Entries there will show up with the destination time.
e,g. a flight departure from Madrid is scheduled for 6pm. It will show in my Google personal calendar and in my Outlook calendar as 2am the next day. It will still show in the Travel calendar as 6pm.
4. I let Ovi Suite synchronize my Nokia phone calendar with Outlook which inserts all entries with times for the appropriate time zone e.g. 2am in Madrid.
5. Now I no longer need to disable automatic Time Zone adjustment in my phone AND lie to the phone that I have NOT changed time zones whenever I change my phone clock for a new country (or Time Zone). In the Madrid example, my calendar entries while in Canada will show a 2am departure and when in Madrid will show a 6pm departure (local time).
Some benefits are:
1. Calendar times will show the local time for all entries.
2. No more calls home at 2am because I forgot the Time Zone differential.
3. No more missed appointments because I made an incorrect time adjustment.
3. Automatic Time Zone correction means my phone is always synchronized with local time. This is significant since I have observed that the phone's internal clock tends to drift. Automatic synchronization automaticallt corrects this.
Points to Consider:
1. Google is my primary calendar because I can control it's directionality.
2. Entries in my Google Travel calendar allow me to see the unadjusted times of Calendar entries, e.g. my Madrid flight is at 6pm. Since Google allows you to see multiple calendars simultaneously, I can see events with both destination and home times.
3. Google will only update one calendar to Outlook (my personal calendar) which is why the Time Zone adjusted times are updated in my Google personal calendar and then to Outlook.
4. Ovi Suite has insufficient controls on updates and sometimes will reinstall Outllok entries which have been deleted or changed. Because Outlook cannot update the Google calendars it or the Nokia calendar cannot corrupt my master calendar on Google.
5. This may not resolve all the convoluted Time Zone boundaries experience in the USA but should help.
6. Have had no problem with DST but also am not dealing with the convoluted Time Zone boundaries experience in the USA.
7. Before and currently I stll place a copy of the input data in the Description section of my Google calendar entries. These will show up in the Nokia Description unadjusted and immune from change due to outside causes.

How do I fix Firefox "untrusted websites" issues due to time change?

I'm on the east coast of the United States. Since the time change, firefox refuses to let me surf to a majority of my websites. I can't use Google because every time I search on something, the "new" google page (the link with the search terms) comes up as untrusted. I'm tired of trying to set exceptions for everything. And some pages (like Yahoo) won't even let me add them as an exception.
This is really getting annoying. I don't want to uninstall and reinstall Firefox because I'll lose my addons and settings.
Any thoughts on how this can be fixed? It worked fine until Sunday. Then everything went fubar. And my computer IS set to the correct new time. I am not going to set it to the summer time because that will screw up other things.
I'm using Windows 7 64 bit.
BTW, I did open up Firefox to look for updates. The updates installed and I'm still having this issue.

British Summer Time - OSX 10.5.8 - time didn't change

Hi there,
British Summer Time is in effect as of last night, when all clocks were supposed to go forward an hour. The time on my iMac is set to update automatically, and has been doing so for the past 5 years...except today. It has remained at GMT, so I've had to change it manually. Changing the setting to 'auto' changes the time back one hour again.
I know Apple has had problems with daylight savings time on the iPhone...but haven't heard of any issues for OSX. Is there a fix for this?
Thanks.

My Iphone and Mac both messed up their time after British summer savings time came in -
Eventually I discovered that the mac had moved my timezone city location to Ghana in Africa; once I relocated to London the auto time on mac was fixed.
On the IPhone, I found that updating the ios to latest version fixed it.

IdM Scheduler and Time Change to Daylight Savings Time GMT to BST

This isn't really a 'question' , but just a topic for discussion.
We're not live yet, but will be by the time the clocks go back. So I'm just interest to hear everyone's experiences and any issues with regards to the switching to / from DST
I did some "interesting" (or not) tests last night to see what happens with Pending Values which are due to take effect at the time change threshold of 01:00 GMT when switching to Daylight Savings Time (BST) GMT +0100.
It seems as if the IdM scheduler keeps going according to UTC or GMT. However any values provisioned to target systems or to local tables using the ddm.datetime8601 system variable are in local time according to the runtime server or SQL server's locale settings.
I set up a task to output from a javascript the current system date
using the following in the functions.
currentTime = new Date();
return currentTime.toString(); // returns Locale Time String
currentTime = new Date();
return currentTime.toUTCString(); // returns UTC Time String
in the same pass I also output the ddm.datetime8601 system parameter and the ddm.time24 system parameter.
This task was to update a comment on an entry and Scheduled to run at 00:00:00 and was executed at 00:00:06 GMT all times were still in GMT as expected.
Local Time: Sun Mar 27 00:00:06 GMT-0000 (GMT) 2011, UTC Time: Sun, 27 Mar 2011 00:00:06 GMT, ddm.datetime8601: 2011-03-27T00:00:06, ddm.time24: 00:00:06
This task was scheduled at 01:00:00 in IdM and was exectued at 01:00:08 GMT by the runtime, and you can see the local time is being correctly reported as 02:00:08 BST. Note also the ddmdatetime8061 is also 02:00:08 i.e. BST.
Local Time: Sun Mar 27 02:00:08 GMT+0100 (BST) 2011, UTC Time: Sun, 27 Mar 2011 01:00:08 GMT, ddm.datetime8601: 2011-03-27T02:00:08, ddm.time24: 02:00:08
In the database the entry values MXI_VALUES ModifyTime field has the GMT / UTC timestamp.
I also set up some pending value objects to be applied at 00:59:59 and 01:30:00 to see if the 01:30:00 would be 'skipped' as the locl clock change would've gone from 00:59:59 to 02:00:00. Well the pending values were correctly applied and expired and no 'lost' transactions happened as a result of the change.
So essentially it seems to me that the IdM runtime and scheduler times are all based on UTC / GMT.
I guess it's only an issue twice a year if you're expecting something to happen at a specific local time 01:00:00 or if you've got a global user base and their account expiry should be in each user's own country's local time. In these cases, it would seem that you'd need to convert the schedule times and pending value times to UTC first before setting them in the database.
Has anyone else had any issues, thoughts, questions or suggestioins on scheduling tasks which span the DST time change when switching to and from Daylight Savings Time.

HT1689 I need to get my iPod to no longer be associated with the original i store account. My husband set it up through his account but now I have my own account. I don't want to go through his every time I want to make a change. how do I make this change

I need to get my iPod to no longer be associated with the original i store account. My husband set it up through his account but now I have my own account. I don't want to go through his every time I want to make a change. how do I make this change?

I am trying to stop using my I-pod under my husband's I-Tune account. It was set up under his account and the only way I can use it under my account is to erase all of the songs my husband loaded on for me. I had heard there is a duration that I-Pods are locked into to one account only, and I am trying to discover how I can use my account without having to erase everything on the I-Pod. I know it sounds confusing but that's the way I-tunes have set it up. thanks for asking.

I have a keynote presentation that includes a significant amount of video. When I edit the keynote slides (not the video slides) how can I save the changes without re-saving the videos (because that takes a VERY long time)?

I have a keynote presentation that includes a significant amount of video. When I edit the keynote slides (not the video slides) how can I save the changes without re-saving the videos (because that takes a VERY long time)? I edit the presentation depending on the audience to which I am presenting.

If you add a new slide with just a text box (therefore a very small amount of data), to an existing presentation then save, Keynote will only save the new content to the file, it wont save pre-existing content as its already included in the file.
The time taken to "save" will be very much shorter than a "save as" when all of the existing content is saved again.

How can i work out the GMT time wherever i am ?

Hi, i'm going crazy with the date/time classes, just can't seem to work it out.
I need to know the current time as a GMT time.
I need to know wherever the program is running, i myself am in Amsterdam GMT+02:00 , my server is located in Canada GMT-04:00 (?)
I parse dates from websites all over the world so i get times in the form of strings of which i know the timezone. I need to store everything in a mysql database and i want the database to contain GMT times only.
I've worked out how to get a string from its timezone into GMT but,
how can i get the current time as GMT ?
somehow i keep getting timeshifts i cannot explain.
this is where i got to:
TimeZone tz_gmt;
tz_gmt = TimeZone.getTimeZone("GMT");
SimpleDateFormat sdformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
sdformat.setTimeZone(tz_gmt);
Timestamp tsGmtnow;
tsGmtnow = Timestamp.valueOf(sdformat.format(new Date()));
Which is fine if i run it in Amsterdam, it gives me the current date/time in GMT, but on the server in Canada it gives me GMT+4 hours. What am i missing ?

found a workaround,
     TimeZone tz_gmt;
     tz_gmt = TimeZone.getTimeZone("GMT");
     TimeZone tz_can;
     tz_can = TimeZone.getTimeZone("GMT-04:00");
     TimeZone tz = TimeZone.getDefault();
     String Stz = tz.getID();
     SimpleDateFormat sdformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
     Timestamp tsGmtnow;
if ( "Europe/Berlin".compareTo(Stz) == 0) {
     // i'm in Europe, go from local time to GMT
     sdformat.setTimeZone(tz_gmt);
     tsGmtnow = Timestamp.valueOf(sdformat.format(new Date()));
} else {
     // i'm in Canada, local time IS gmt
     sdformat.setTimeZone(tz_can);
     tsGmtnow = Timestamp.valueOf(sdformat.format(new Date()));
out.println(tsGmtnow.toString());
the default timezone returns either:
Europe/Canada
GMT-04:00
somehow the GMT-04:00 get ignored by the formatter

How do get current date/time in GMT?

Is there any way to get the current date and time in GMT (while my current locale is not GMT)?
In Java I can do this:
long currenttime = System.currentTimeMillis();
java.text.SimpleDateFormat df = new java.text.SimpleDateFormat("yyyy/MM/dd HH:mm:ss z");
df.setTimeZone(java.util.TimeZone.getTimeZone("GMT"));
java.util.Date date = new java.util.Date();
date.setTime(currenttime);But, there seems to be no way to do the equivalent in BPEL in SOA Suite.
I did some research and I think I could appy the XPath 2.0 function adjust-dateTime-to-timezone() to the current time, but that function is not available.
Using SOA SUite 11.1.13.0.
THanks.

have you tried changing the stylesheet version in the xsl to 2.0 and then try the function again ?
by changing this version it was possible to use newer functions, which weren't available in the designer
