How do I sync the time servers of my gateways?

Use a Central Time Server or public NTP source.

There are several ways to accomplish this depending on how isolated your local network may be. If the network has no public internet access, consider using a Central Time server such as ATS (Absolute Time Server). However, if your network has open access to the internet consider using a public NTP source such as ‘pool.ntp.org’.

Please refer to the following for additional information:

• Install Time Server
