So this morning I was looking at my computer clock. Something was off – namely the time had set itself one hour ahead. “That’s odd” I thought. I know I had setup NTP or Network Time Protocol on my Windows 10 machine.

Couldn’t see the problem before I left for work. But I mentioned it to co-worker and said “I bet it’s because it’s using Microsoft’s NTP server.”

I was correct. Got home and change it to NIST time servers and presto change-o voila – the time is once again scarily accurate.

I further wonder – how many other people are running Windows 10 with NTP turned on and using Microsoft time servers and had the same problem?

I also wonder – could it be that the Microsoft IP I blocked a couple months back be their NTP server? Nah – it’s not.
