Domain Controller resets time ahead one hour on reboot


  • I have a Windows 2003 R2 domain controller that is running on a Windows 2012 Hyper-V cluster. Time sync between the host and guest are disabled. The last two times the Domain Controller has been rebooted, time has jumped ahead one hour on the Domain Controller which is also our NTP server for the company. Our DC's have been virtualized for 5-6 years, first on VMware, then on hyper-v 2008 r2 now on 2012.

    I have verified that hosts and guests are configured for the correct time zone and the DST is enabled. The first incident occurred the weekend after the time change, so I thought maybe their was some DST issue.

    Any thought on why it would jump ahead exactly one hour after reboot?
