For the past several weeks since reinstalling Windows on my laptop, my time has been off for a minute or so. I opened the Date/Time control panel. Oddly, or maybe I never noticed it before, but the Internet Time tab didn't show initially. However, it appeared after a delay of a few seconds.

I clicked on Change Settings and thought I found the problem. The check box for synching time was not checked. I checked it and also clicked Update Now with the server set to time.nist.gov.

I opened the NIST time server and surprisingly my time was still off by about 30 seconds. So I switched to time.windows.com and rechecked. Now I'm off by 10 seconds.

That's not good enough and I frankly have no faith that my Windows system can faithfully do this mundane task for me. Do I need to manually update every day?
