Difference between LV 6.1 and LV 7.0 - Date\Time Format

I found different behviour of numeric controls in Date/Time format, or
in "Seconds to Date\Time String" function in LV6.1 and LV7.0
In LV 6.1:
Absolute time in seconds is formated in control with date/time format,
output depends on local time format on computer, where this VI runs.
So if I start LabView on machine with specific time zone, and for
example DST on, the output was changed by these settings. ANY number
of second is handled by this settings.
In LV 7.0:
Output still depends on specific time zone, but the use of the DST
on/off depends on absolute time value. So if the number represents
absolute time which fits period when DST was off, the output is
wihtout DST, even if the DST is on when this vi runs.
The solution in LV 7.0 is much more better than in LV 6.1, but ...
If data are measured and stored (store of absoulte time DBL) in one
time zone, and if they are processed in different time zone (for
exapmle where DST change is in different time), the data
representation is wrong.
In LV 6.1 it was not correct too, but anyway there was a way how to
solve this problem:
I stored absolute time DBL and GMT delta for every time stamp. When I
process this stored data on different computer with different time
zone, I recalculate time stamps in this way:
absolute time + stored GMT delta - GMT delta of computer where data
are presented.
So in final I have correct time does not matter on time zone or any
other settings which are on computer where are data presented.
But on LV 7.0, the GMT delta is not constant for every data and this
algorithm is useless. I can simply show correct time when data are
from same time zone without any calculation, but it is almost
imposible to correct show data
from different time zone.
My question is:
Is there any "ini file item", which can tell LabView 7.0 to use time
representation style as in LV 6.1 ?
Thank you and best regards
Jiri Hula

Thanks for the well written question.
Unfortunately, there is no ini token or any way of specifying LabVIEW use the LV 6.1 style.
I am attaching a LabVIEW 7.0 VI that calculates the UTC Offset for a given time value (I don't think the same code would work correctly in LabVIEW 6.1). The VI comments are:
The attached VI will take Daylight Saving and Time zone into account to compute the offset in seconds from UTC Time to the Local time (as specified by the computer). Note: This VI can aid in converting from Local Time to UTC time, but not in converting from one Timezone to another.
I hope it helps. Basically, your data is in UTC (absolute time) as it has always been, but LabVIEW 7.0 changed the way it displays the UTC data (trying to be more correct). If you wish to display it the way it was in LabVIEW 6.1, things are going to get a little tricky. LabVIEW 6.1 displayed the same DBL absolute time differently depending on if the current computer time was in DST or not. To get this behavior in LabVIEW 7.0, the equation:
absolute time + stored GMT delta - GMT delta of computer where data are presented
is still correct, but for LabVIEW 7.0 the GMT deltas now vary depending on whether the absolute time is in DST or not. It may be possible to convert the GMT offset you have saved from LabVIEW 6.1 into a set or pair of UTC Offsets. This would require a knowledge of what the DST state was for each of the data points in question.
The DST state or GMT/UTC offset that the computer currently is using may be obtained from the attached VI.
The absolute time is stored in GMT/UTC so that in different time zones it will still equate to the same time, even though it will be displayed differently. Another data format (such as storing the Hour, Minute, Second, Day, Month, Year; or storing the date as a string) might be more appropriate if the time should be displayed as the same local time regardless of the time zone.
I hope this helps. Please respond if you have any comments or questions.

Convert date/time to a value in second

Hello,
I want to convert a basic date time variable into a numeric one corresponding to the time (in second) passed since January,1,1970 in order to put it in a SQL statment as a criteria.
Is someone able to help me ?
Regards

If you have an java.util.Date object you can call getTime() method on it. It will return milliseconds. Just divide it on 1000. Here is example code:
java.util.Date date = new java.util.GregorianCalendar(2001, 7, 6).getTime();
long seconds = date.getTime() / 1000;
//Your code
Best regards, Alex.

Date/Time to Second

I am trying to create a custom timestamp with the node Date/Time to Second. I am not sure why, but regardless of what input I feed it, I always get 00:00:00.000 PM MM/DD/YYYY. Why is that? See code.
Kudos and Accepted as Solution are welcome!

My guess is in the month part.
If you enter a month <1 or >12 the 'Date/Time to Seconds' will return what you are seeing.
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

Thumbnail date & time - how to display seconds?

Also, in our previous version of Bridge we had our preview settings so that we could view the date & time below the filename. The time format was H:M:S. Now in Bridge CS4, the seconds do not appear. Please advise on this setting.
Thank you.

I can see the seconds in all files in CS4 when the Content panel is set to view as Details or as List in the View menu, but not when set to view as Thumbnails, where only some files show them. A possible bug?
Never paid attention to seconds in earlier versions.

When I run this VI "Waveform Time to Date Time String" in LabView 7.0 it will not pass decimals of seconds.

When I run this VI "Waveform Time to Date Time String" in LabView 7.0 it will not pass decimals of seconds. From decimals of inputline. If i disconnect the input to the subVI "Get Date/Time string vi" it will work propperly, it also doses if I reconnect it. I use LabViev 7.0.
So the problem i solved, but i dosent understund why it works in this way. Does it indicate other problems which will make my researchprogram unrelaible ?

Hello.
I checked your vi and it fails as you state.
It runs fine if: 1 Convert number to timestamp OR
2 Wire a constant to want seconds?
In labview 7.1, no problems.
I think is a job for NI engeniers.
Hope it helps

Calendar now splits my entries into 2 separate entries. 1 entry lists date/time/name. The second entry lists notes

Calendar now splits my entries into 2 separate entries. 1 entry lists date/time/name. The second entry lists notes and alerts. I can delete the date/time one, but not the alert entry. That means I will get all the alerts even if I deleted the original entry. It shows up as two separate entries for each one entry. This happened after the Yosemite install.

Date / Time System fields - inconsistent

This is a weird one...please bear with me
Before I begin...note that this is not a problem that is difficult to fix, I'm just interested in better understanding why the system fields are behaving the way they are.
We have 20 or so programs that use a function module to create a file header that includes a date/time stamp. The programs also place a trailer with a date/time stamp that should match the one in the header. However, the programmer used different system fields (after a GET TIME statement) to create the date/time stamp in the trailer. On occasion, the date/time stamp comes out different.
Here's the code (sry about all caps):
GET TIME.
CONCATENATE SY-DATUM SY-UZEIT INTO BATCHID.
CALL FUNCTION 'Z_YADAYADA'
       EXPORTING
            FILE_ID              = P_FILEID
            REFRESH_TYPE         = P_REFTYP
            START_PERIOD         = START_PER
            END_PERIOD           = END_PER
       IMPORTING
            STRING255            = OUTPUTSTRING
       EXCEPTIONS
            INVALID_REFRESH_TYPE = 1
            INVALID_BATCH_ID     = 2.
...sy-subrc check...
TRANSFER OUTPUTSTRING TO P_FILE1. <--header output
CONCATENATE L_TRL BATCHID COUNT T_TOTAL SPACE
              INTO OUTPUTSTRING SEPARATED BY L_DEL.
CONDENSE OUTPUTSTRING NO-GAPS.
TRANSFER OUTPUTSTRING TO P_FILE1. <--trailer output
inside function module *****
CONCATENATE: SY-DATLO SY-TIMLO INTO DATESTAMP,
               SY-SYSID SY-MANDT INTO MACHINE_NAME.
CONDENSE: DATESTAMP, MACHINE_NAME NO-GAPS.
CONCATENATE C_HDR DATESTAMP FILE_ID MACHINE_NAME
              SY-CPROG ' ' REFRESH_TYPE START_PERIOD
              END_PERIOD DATESTAMP
              INTO STRING255 SEPARATED BY '~'.
CONDENSE: STRING255 NO-GAPS.
You can see that the function uses SY-DATLO and SY-TIMLO for creation of the header, while SY-DATUM and SY-UZEIT are used for the trailer. What's wierd is that sometimes the trailer has a date/time stamp that is 1 second <b>greater</b> than the header, despite the fact that it is stored in the BATCHID variable <b>before</b> the header is created.
Any help, references, explanations greatly appreciated (and rewarded with points)

Hi Brian
Here is the related part from the weblog of ABAP expert Horst Keller. Hope it may help. For the full document, you can visit <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.sdn.wcm.compound.docs/library/uuid/f1391fc3-0301-0010-d384-fccd036f1c67">here</a>.
The values of all system fields in this table are implicitly set when the program is started, every time a screen layout of a screen is sent, and when the internal mode is set. The GET TIME command explicitly updates the system fields, except for sy-dayst, sy-fdayw and sy-tzone.
With the exception of sy-datlo and sy-timlo, all system fields refer to the local date and time of the current SAP system. The ABAP runtime environment clock is synchronized with the database server clock at regular intervals in order to calculate the local time of the SAP system. During the synchronization process, the ABAP runtime environment clock is set to the database server clock. Because this happens on all application servers in an SAP system, the ABAP runtime environment clock is synchronous with the clocks on all other application servers and with the database system clock, and thus shows the local time of the entire SAP system. The time zone on which the local time of an SAP system is based is the only entry in the database table TTZCU.
The content of sy-zonlo is taken from the user master record of the current user. The values of sy-datlo and sy-timlo are calculated from sy-datum and sy-uzeit and from the time zone of the SAP system for the time zone in sy-zonlo. If the user master record does not contain a time zone, or if it contains an invalid or an inactive time zone, sy-datlo and sy-timlo are set to the values of sy-datum and sy-uzeit. All valid time zones are defined in table TTZZ.
Is't the naming of sy-datum and sy-uzeit really geeky?
Time Stamps
The above system fields for date and time are not sufficient for many requirements of determining unique points in time: They represent local times and the values are measured in seconds. For more exact date and time determination, you use time stamps.
A time stamp represents date and time in the form YYYYMMDDHHMMSS. YYYY is the year, MM the month, DD the day, HH the hour, MM the minutes and SS the seconds. There is a short form and a long form. In the long form, the format specified above additionally contains 7 decimal places for fractions of seconds, which allows for an accuracy of up to 100 ns. The maximum time resolution depends on the operating system of the application server and may be less.
A valid time stamp must contain values whose date and time specifications before the decimal separator correspond to valid values for the data types d and t. Time stamps in this form are always considered as UTC (Universal Time Coordinated, basis for calculating worldwide time specifications; the UTC reference time is based on Greenwich Mean Time, GMT, but is not a time zone; it has no daylight saving time or summer time) time stamps when processed with the corresponding statements. You use the statement GET TIME STAMP to create a time stamp that represents the current UTC reference time.

Get date-time from .lvm

With Labview I've created a .lvm file with 6 colums of data. The .lvm also contains a x value (+1 for each row) so i'm saving 1 row of data every second.
If I plot the data in Diadem the X-axis shows up as relative time, but I want to see the absolute time (date+time). All the information is to do this is present in the header of the .lvm, but I cant find the setting to do this!
Thank in advance!

Hi Inspectation,
OK, I got your *.LVM file, and all is clear. The problem in this case is that DIAdem 2010 and prior versions are hiding the absolute date/time property of the waveform from you in an attempt not to confuse you. But since that's exacty what you want to see, this approach ends up being very confusing indeed, even though it works great for most of our customers.
The good news is that the LVM DataPlugin is parsing the absolute date/time property for each channel, and that property is being loaded (invisibly) into the Data Portal, so you can run a VBScript to fish out that information and create a new DateTime channel to plot the data against on the X axis:
OPTION EXPLICIT
Dim GroupIdx, ChanIdx
GroupIdx = GroupDefaultGet
IF GroupChnCount(GroupIdx) > 0 THEN
ChanIdx = CNoXGet(GroupIdx, 1)
Call WfmToDateWfm(ChanIdx, "DateTime")
Call ChnRenumber
END IF
Function WfmToDateWfm(Channel, DateTimeChanName)
Dim ChnStartTime, OffStartTime, ChnDeltaTime, RelStartTime, RelStopTime, DateTimeChannel
IF ChnPropValGet(Channel, "waveform") <> "Yes" THEN Exit Function
ChnStartTime = CDbl(CDate(ChnPropValGet(Channel, "wf_start_time")))
OffStartTime = ChnPropValGet(Channel, "wf_start_offset")
ChnDeltaTime = ChnPropValGet(Channel, "wf_increment")
RelStartTime = 24*3600*(Trunc(ChnStartTime) + 693958 + Abs(Frac(ChnStartTime))) + OffStartTime
RelStopTime = RelStartTime + ChnDeltaTime*(ChnLength(Channel) - 1)
IF DateTimeChanName = "" THEN DateTimeChanName = ChnName(Channel) & " DateTime"
Call GroupDefaultSet(ChnGroup(Channel))
DateTimeChannel = ChnLinGen("/" & DateTimeChanName, RelStartTime, RelStopTime, ChnLength(Channel))
ChnFormat(DateTimeChannel) = "Time"
Call ChnMove(DateTimeChannel, ChnGroup(Channel), ChnIndex(Channel))
WfmToDateWfm = DateTimeChannel
End Function ' WfmToDateWfm()

Aperture 3.2: renaming based on date/time doesn't work properly

While importing I rename my photos based on the date/time they were taken.
In Aperture 3.1.3 this worked perfectly fine; for photos taken within the same second Aperture added an index number for the second, third etc. photo automatically.
In Aperture 3.2 this doesn't work any longer; Aperture simply doesn't import photo number 2, 3 etc. of that particular one second.
Note: I store the original files outside the aperture library, all run under snow leopard on an iMac i7. And as I said this worked fine under 3.1.
Does anyone have an idea?

Thanks all for the response
Leonie, here are the details of what I do/experience:
a) Aperture message after import
b) I import pairs and rename them as follows “IMG_{Image Date}_{Image_Time}” (I know all the disadvantages of this but old habits are hard to break… and for me it still works fine)
c) Difference of the images that are imported / not imported is solely the hundredth of the second when they were taken. Of my test series only the first image has been imported:
DSC_4903.jpg(2011/10/19 22:49:50.08)
DSC_4904.jpg(2011/10/19 22:49:50.25)
DSC_4905.jpg(2011/10/19 22:49:50.43)
DSC_4906.jpg(2011/10/19 22:49:50.60)
DSC_4907.jpg(2011/10/19 22:49:50.80)
d) I import via the import panel: Import in new project – storefiles in particular folder (not Aperture library) – subfolder ‘imageyear/month” – rename as described above – import both
Doug, after some trial and error I agree with your thoughts, Aperture apparently simply lost its automatic indexes ‘-1’, ‘-2’ etc. and – what is good - doesn’t overwrite the first with the second and the third image... As you suggest there are different options to make the images unique. Most simple would be to add {index #} or {sequence #} or {counter}, all would do and I probably will choose one of them. Or I will downgrade back to 3.1.3 (do have backups) and wait until Apple fixes this.
Kirby, turnoff “Don’t import duplicates” was a good idea but didn’t solve it. But your naming convention actually ensures the uniqueness of the files.

WARNING: Adjust Date & Time doesn't work

I bought Aperture 2.0 because I was thrilled they finally have an adjust date/time feature. The interface is great, but it simply doesn't work.
I was trying to adjust a batch of images by 30 seconds to get it in sync with another camera, however, it ended up adjusting it by 30 minutes!
I was trying to get the time to change from:
1:33:09 PM to
1:32:39 PM
and the image ended up at
1:00:33 PM
Anyone else had a similar problem or a solution for this serious bug?

I added my own topic earlier this morning. In my case, it's working just fine if my primary image is RAW and all selected images are also RAW (Canon 300D). It also works just fine if the primary and all selected images are JPEG (from either a Canon S3 or a Panasonic Lumix digicam). However, if the primary image is RAW (Canon 300D) and any selected images are JPEG (anything modified in iPhoto, or originally shot in JPEG from by Canon 300D), all **** breaks loose on those JPEG image dates.
I have some which went back a few months, but most of them jumped forward between 6 months and 2 years.
Again, something is severely broken with this function.
Anyone know how to get the original dates back? Please? I'm setting aside several hours tonight to restore the pre-2.0 backup, export my 2.0-only projects, and import those back in, just forgetting any changes I'd made to historical project files in the meantime. This really *****.

How can I display date+time and not the point number in excell?

Hi everyone,
Could anybody tell me how I can save date + time to a file, so that I can display on a diagram(excel) : date+time in (ox) and data (oy)? :
My program sets in (ox) the point number and not the date+time....( although date and time are written correctly in the column...)
Any help would be great,
Thanks,
regards,
Marc

hi there,
excel uses 01.01.1900 00:00 as the time offset, LabVIEW uses 01.01.1904 02:00, so you can't display the correct datetime in excel when you write the time as a fractional number of seconds from LabVIEW. you must format the datetime in LabVIEW to a string and write that to the column. use the "Format Date/Time String" - function and for example "%d.%m.%Y %H:%M:%S%3u" as the format string (see the functions help for more examples). you also could format your data to a string using "Format Into String" - function and write the file as a 2D string array. the decimal point you have to use depends on your system and its settings, but you can specify the decimal point in the Format string like "%.;%f" (means fractional number with point as decimal point).

IPhoto, sort by date is not a true date/time sort

In iPhoto, sort by date is not a true date/time sort. If you have two cameras with there own naming convention iPhoto sorts filename by date separating the two cameras in the view. Is there a way to sort by DATE&TIME ONLY?

Using two cameras using iPhoto to upload pictures.
Both cameras are set to the correct time and date.
Connect camera ONE filenames IMGP0101
By default:
No event name
Split events checked
Select import 12 photos
Creates events:
Untitled event December 27, 2013
In order by time
Untitled event December 28, 2013
In order by time
Untitled event December 29, 2013
In order by time
Untitled event December 30, 2013
Connect camera TWO filenames IMG_1101
By default:
No event name
Split events checked
Select import 12 photos
Creates events:
Untitled event December 28, 2013
In order by time
Untitled event December 29, 2013
In order by time
Untitled event December 30, 2013
Now I have 2 events for each of December 28, 29 and 30 they are not all under the same event name. My only option is to click and drag the pictures from the second set of events to the first set of events then they are in order. This is a real pain to do. There needs to be a way to reset the event dates so all pictures from both cameras end up in the right event date.
