GPS timestamp to tdms file

[CART-2_Detectives]

Hello all,

Is there any way to overwrite the timestamp written to a TDMS file with a timestamp from a GPS card (6682H module)? Also, will this stamp be synced exactly to the first sample taken? Thanks!

There is no direct way to modify data in a TDMS file. But you can accomplish that by read all data out and write to a new file with the channels you want to replace.

You can edit the timestamp field in the TDMS file.

It is quit simple.

Refer the following examples.

C:\Program Files\National Instruments\LabVIEW 2011\examples\file\plat-tdms.llb\TDMS - Write data (time domain).vi

C:\Program Files\National Instruments\LabVIEW 2011\vi.lib\Utility\tdmsutil.llb\TDMS - File Viewer.vi

Now, what is the data type used in the TDMS file?

Share the data type or the sample code, for more assistance.
