Windows Clock on PXI Controller Repeatedly Loses Time

Issue Details

• My PXI or PXIe controller's clock repeatedly loses its time. Why is this happening?
• When I set the hour for my controller it goes back to an incorrect date/time after a couple minutes.
• Why does my Windows time reset to 12:00 AM every time I boot my PXI controller?
• My PXI computer doesn't retain the operating system time between boots.

Solution

1. Verify the Windows Time Service

   • Press Windows Key + R

   • Type services.msc and hit enter

   • Look for the “Windows Time” service and double click it

   • Set the Startup Type to Automatic and click the Start button. Verify the status is set to Running.

   • Try to change the time settings and check if the issue is resolved

2. Ensure that the current version of the BIOS is up to date. Please see Determining and Upgrading PXI and VXI Embedded Controller BIOS Versions  for more information.
3. Replace the CMOS battery in the controller. Please see PXI and PXIe Controllers Replace Battery for more information.
