PCs on my network pull their time from our dc which pulls its time from a ntp server. My dc is a vm machine. Can anyone give me some insight as to why this time is faster by 4 to 5 min than a cell phone or atomic clock?

Not only do I want to know why this is but I would also like to resolve this issue.

    Accepted Solution

    It depends on NTP server you use. Check if you use the same time servers on atomic clock and active directory time server.
