You can try configuring it to user a Time Server.

virtual server 2012

Assuming you havent set this DC to sync with an external NTP server, are you sure the time is correct on the host machine that this VM is running on?

[kwesi Yaro]

yes the time on the host machine is correct!

[JorgeM]

if the DC is not configured to sync with an external NTP server, then it assumes it has the authoritative time and because of that, the time would not change on its own. I mentioned for you to check the host server because VMs will generally take upon the time that the host server has.

have you verified the NTP settings? Did you check the system log in Event viewer? the time sync should be logged there.
