Hi,
Thanks for contacting National Instruments. The behavior you are seeing is actually quite expected and correct. The reason you are seeing the difference in times is because the RT controller and your PC may be using different time zone settings. To get the same time for both machines, you need to set both of to the same time zone. E.g., if your PC is in the Central Time Zone, you need to set your PXI-RT controller to be same. To set this, go to MAX » Remote Systems » [RT Controller] and click on the System Settings tab. You can then select a time zone for your RT controller.
Let me explain what happens if the time zones are different:
On RT controller, if the time zone is set to Coordinated Universal Time (GMT), and if you copy the seconds over to your PC, you will the time will be off by 6 hours (if your PC is in the Central Time Zone). So as I mentioned, ensure that the timezone for the controller is the same as for the PC. The timestamp datatype actually accesses the local timezone and does an offset, so having the same timezone on both machines cancels that offset.
Hope this helps.
