GitHub Enterprise automatically synchronizes its clock by connecting to NTP servers. If for some reason the clock starts to drift, there are a few ways to re-adjust it.

You can:

  • Use the ntpdate command to synchronize the server with an NTP server, e.g. ntpdate

  • Set new NTP servers if your installation cannot access the default ones.

  • Prevent your hypervisor from trying to set the virtual machine's clock. For example, you may be able to accomplish this on VMware by unselecting Synchronize guest time with host.
