The time displayed by WIndows 10 is over 30 seconds slow even though I shut it down and restarted my computer less than 15 hours ago. I can’t find a way to force W10 to synch the clock with a time server.

I too have noted the @30+ second discrepancy. This appears to be a permissions issue. 

I have a little utility called “AboutTime” that I have been using for 15+ years to sync time across my networks and with internet time servers.  This util has been rock solid for all that time and still runs under Win 10. 

However even using this to sync with a local SMTP server, I was still getting a 30000+ ms offset.

Just for the **** of it, I tried running AboutTime under “Run as Admin…” and low and behold, my offset was now under 2 ms. This was syncing to either NIST or my local server.

The strange thing is that I generally run that util from an admin account. So I should not need to “Run as Admin…” but there it is. 

Clearly a bug, err… I mean “feature” in Windows 10.
