Need help understanding TDMS usage

[CoastalMaineBird]

Obviously I have overestimated the capabilities of Diadem to provide easy ways to look at data.

I used your two-express-VI idea to write a file.

the SIMULATE SIGNAL vi, I set to use ABSOLUTE time. 50 samples at 10 Hz sampling of a 2 Hz signal.

I then wrote to a TDMS file.

In DIADEM, you can clearly see that the EXPTIMESTAMP and EXPSTARTTIMESTAMP properties are there. Yet it won't show me the time.

Looking at the code to the TDMS FILE VIEWER, it doesn't do anything to  the data.  It just reads the WAVEFORMS, and plots them.

That means the data is recorded properly, it's just Diadem doesn't behave as I expected.

Well, it looks like it IS Diadem's fault:

I found these on the Diadem Forum:

There's no way in DIAdem 2012 to configure the format of a Date/Time X axis in the VIEW panel.  You can format the X-axis all you want in REPORT, but in VIEW you're stuck with the auto-formatting of a Date/Time X axis.

As Brad noted above, the X axis may be customized in a REPORT but not in VIEW.  VIEW is mainly for quick verification of your data set, whereas REPORT allows you to create custom reports for the presentation of your data.  

Please let me know if you would like any further clarification.

Warm Regards,
