How to Convert Time Stamp to String for Filename use

I'm writing an Labview application in which I would like to convert pull time stamp infor from Time Stamp VI and convert to string so I can use to append as part of filename.
The fomat that I want may look something like basefilename081208_1300. This would represent a file name that has elements consisting of the date 08/12/08 and 13:00 hours zulu.

Hello:
Use the Format Date/Time String VI, and use as the format string the following: %d%m%y_%H%M
This way you'll get the date string you want.
Then concatenate the output to other strings you need to name your file.
I've attached an screenshot.
Hope this helps.

Jeff,
I just did it like this. Do you forsee any problems?
Well, what is the output? Do you foresee a problem? The LabVIEW Help is quite clear on the format. The very first sentence of the Help file for the Format Date Time String provide a link to the codes: http://zone.ni.com/reference/en-XX/help/371361H-01/glang/codes_for_time_format_str/

How to convert Time stamp format in CR

Dear all Expert,
I have a question. I have a field in my CR which is date time. It show 24.03.2011 03:30:00 in the tables. But when i drop this field in my CR, it become 20,100,906,080,000.00. How to convert it to 24.03.2011 03:30:00 in CR?
Thank You.

Hi Alex,
If cdatetime won't work, try the following by creating a formula . Note : replace your time with database date field i.e. date_4.
WhilePrintingRecords;
Stringvar date4:=totext('24.03.2011 03:30:00');
Numbervar yr;
Numbervar mon;
Numbervar dt;
numbervar hh;
numbervar mm;
numbervar ss;
yr:=tonumber(mid(date4,7,4));
mon:=tonumber(mid(date4,4,2));
dt:=tonumber(left(date4,2));
hh:=tonumber(mid(date4,12,2));
mm:=tonumber(mid(date4,15,2));
ss:=tonumber(mid(date4,18,2));
cdatetime(yr,mon,dt,hh,mm,ss);
Thanks,

Try this way:
CONVERT TIME STAMP <tst> TIME ZONE <tz> INTO DATE <d> TIME <t>.
CONVERT DATE <d> TIME <t> INTO TIME STAMP <tst> TIME ZONE <tz>.
<tst> is of type P(8) or P(11) with 7 decimal places
<tz> of type C(6)

How to get time stamp as a number

The get date/time vi gives time stamp in string or cluster. I want time stamp as number because i have to give time stamp number to a build array along with another number. How do i get this , say for example time as 14.32

do u mean this?

How to write time stamp to a file

Hi,
I'm using LabVIEW 8.2 and for my simulations purpose I've to store my data with time stamp (seconds having 6 digit precision ) in a text file.
I'm using get time vi to get the time of the host computer on a 6 point precision (which I've attached also). My problem is I'm unable to convert this time stamp into string which can be written to text file directly. I would prefer to avoid the "unbundle cluster" which gives me individual elements (like seconds,date,time,year,day of the year, etc) and them convert each of them into a string.
Looking to hear from any one of you soon,
Regards

Hi Roiht
You will never achieve 6 digits precision with the "get date/ time i seconds function" Perhaps 1 if you are lucky. But you can convert the time to string using the "format data/time string" function. You find it in the same palette as the other time functions.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Error when converting time stamp in date time time zone CST in IC

Hi Experts,
We have recently upgraded from CRM 5.0 to CRM 2007. We are using IC WEB Employee interaction center.
so when agent create service ticket in interaction center and close the ticket on same day we are getting an error saying Error when converting time stamp in date time time zone CST.
we thought there may be problem while installing SAP CRM by basis team in time zone, but we did not find any problem.
So please advice how to resolve this issue.
Regards,
Teja

Hi Teja,
I saw a similar message, and it was resolved by adding a timezone to the user profile defaults tab in SU3. I believe the system has been configured to convert between users' timezone and the system timezone, therefore it needs to know each users' timezone.

Adjusting time stamp of AI waveform when using pause triggering

Hi Everybody,
I've written a VI that acquires data (AI) at specified time intervals
by using pause triggering and a counter signal, but the resulting time
stamps associated with the data points in the AI waveform are NOT the
actual time relative to the start of the initial acquisition. I was
thinking of modifying the time stamps (post-acquisition) for each set
of data points per interval by adding the "off" time as set by the
counter signal, thereby adjusting the time stamps of the data to real
time. I then have a subVI that will convert the time stamps to elapsed
time. I also have an AO waveform being generated at the same time, and
was wondering if I could somehow use those time stamps values if they
were synced to the AI somehow, although this seems more difficult. The
adjustment does not need to be extremely accurate, and can vary on the
order of seconds (e.g., the last data point could be at 9990 seconds
for an acquisition that actually ended after 10000 seconds). Any
suggestions?
As an aside, the important point of this part of my program is to
reduce the amount of data being collected. I need a high sampling rate
to acquire waveforms with pulse widths on the order of milliseconds,
but typically run the experiment overnight (+12 hrs.) so the files get
really big (e.g., 3 GB!). I could try writing to binary files, but I
haven't figured out how to read the file and then split the data into
smaller files of user-defined size that can then be converted to
text/.xls files. If you have any ideas on how I might do this as well,
I'd greatly appreciate the help! Thanks!
Unagi

Unagi,
I am not exactly sure what you are trying to do, but I can
take a guess. When performing analog input measurements the waveform is
composed of t0, dt and Y. You can manipulate any of these values after
the data has been acquired. If you set up the task the waveform should
contain an absolute time, not relative. If relative is required, as you
suggested, this can be done post acquisition with the build waveform components
vi.
I do not understand exactly what you want do with the
timestamps for the analog output. Do you
want to use the relative time computed from the analog input data for the
analog output waveform? If so, you could
build a waveform and use the t0, dt from the analog input processed/relative
time waveform. Again this would be done with the build waveform components
vi.
Finally, a binary file would reduce the amount of memory
required when saving your data. A binary file is fairly simple to save
and open in LabVIEW. There are a couple examples in NI Example Finder (i.e.
Write Binary File and Read Binary File) that show you how to write and read
binary files. If you write the data to a binary file during acquisition,
and modify/split it later you could open the binary file, retrieve the data in
LabVIEW, and write a small subset to a text file. Alternatively, you could
perform some analysis of the data during acquisition and only save the set of
data that you require post acquisition.

How to setup Time stamp for CO-PA.

Hello Friends,
I have created CO-PA datasource in KEB0. Defaultly, the delta method has been selected as
'Generic delta'. But, I need time stamp for delta process.
Where can I setup time stamp for CO-PA data source?
Thanks
Sumanth

Hi,
You need not maintain the timestamp for COPA separately.
A generic data source for which delta based on the timestamp is automatically created.
By default the delta for CO-PA is based on timestamp and you need not do it manually.
Once you do an init for this and see an entry in RSA7 for the COPA data source then you check the option delta status in front of the data source...just click on it and it will tell you upon which field the delta for data source is based...you will find that for CO-PA its by default always timestamp.
Thanks

Converting time stamp in waveform to seconds

Hello,
I would like to convert the time stamp in a waveform (coming from 'AI Sample Channel') into seconds. Currently when I read the waveform into a file I get a format that looks like
18:00:47.453000
Any help you can offer would be greatly appreciated, it seems like this should be easy to do?
Thanks,
Cullen

In the attached example, I compare converting the datestamp to seconds by converting to double, to extended precision and doing a delta directly on the timestamp iteself (then converting).
Running the VI showed the same results (using Win-XP) for all three cases. Unless you have a better OS, then the top example would probably do.
At least the example will show you how to convert to seconds (in 50ms steps for the example), and how to do it using the array directly (polymorphic functions).
Hope it helps,
RayR
