Configuring time synchronization

GitHub Enterprise Server automatically synchronizes its clock by connecting to NTP servers. You can set the NTP servers that are used to synchronize the clock, or you can use the default NTP servers.

Changing the default NTP servers

  1. À partir d’un compte d’administration sur GitHub Enterprise Server, cliquez sur en haut à droite de n’importe quelle page.
  2. Si vous ne figurez pas déjà sur la page « Administrateur du site », dans le coin supérieur gauche, cliquez sur Administrateur du site.
  3. Dans la barre latérale «  Administrateur de site », cliquez sur Management Console .
  4. In the "Settings" sidebar, click Time.
  5. Under "Primary NTP server," type the hostname of the primary NTP server.
  6. Under "Secondary NTP server," type the hostname of the secondary NTP server.
  7. Under the "Settings" sidebar, click Save settings.
  8. Wait for the configuration run to complete.

Correcting a large time drift

The NTP protocol continuously corrects small time synchronization discrepancies. You can use the administrative shell to synchronize time immediately.

Notes:

  • You can't modify the Coordinated Universal Time (UTC) zone.
  • You should prevent your hypervisor from trying to set the virtual machine's clock. For more information, see the documentation provided by the virtualization provider.
  • Use the chronyc command to synchronize the server with the configured NTP server. For example:
sudo chronyc -a makestep
