Normally that is true and I could see my system trying to communicate with NIST is it where set to synchronize with NIST. However it is not set to synchronize with NIST it is set to sync with time.windows.com
Also this just started happening with in the last week. I also checked the time on my system and it is in sync with current pacific standard time.
So anyone have any idea how to locate the program that is scanning my UDP ports an trying to communicate with NIST?
Windows 7 x64 Ultimate
Attached is a picture of the scans.
