How to query hardware clock(RTC) to synchronize with system time in windows 10 IOT LTSC

_{Thursday, March 26, 2020 12:41 PM}

Hi, 

Are there any ways to let the windows 10 IOT LTSC to sync with hardware clock (RTC) in motherboard to correct the clock without the restart quite often/internet/time server?

For example, do some setting/use window api/task scheduler to sync/something like hwclock/anything

I raise this question due to there is system time drift around 20-30 seconds in a week while RTC is still accurate.

I know that by restart PC, the system time will read the RTC and correct the system time but The PC running the window IOT is used for critical function, so not encourage to restart often and there will be no internet connection.

Windows version: 1809

Please advise.

Thank you.

Ong YY
