DAQmx Waveform Timestamp

Hi there,

 

Here i am getting weird problem while acquiring data from PXI 6255 (DAQ-mx) continuously in waveform manner.

 

Waveform acquired from device contains timestamp of data acquisition.. (I already go through tutorial of timestamp source and reliability) ..

 

This timestamp is referenced to clock of PXI system (as i am using this card in PXI RT System)

 

Although my RT system is configured in GMT + 5:30 clock setting but timestamp acquired in waveform in GMT + 6:30 ALWAYS (1 hour letter the actual time)

 

I tried number of things and figured out that daqmx uses system time configured in UTC + 5:30 not GMT + 5:30. (although both are same time but PXI RT system is not considering both as a same)

 

PXI RT system is considering UTC + 5:30 = GMT + 6:30 from my results of efforts (If you change GMT timezone to UTC, your original time will be replaced by 1 hour later).

 

Hope i have conveyed my problem. Please let me know if further information is required
