Synchronizing Cluster Server Clocks

Standardizing the time zones using these steps to allow the log files to be time stamped uniformly for failover purposes and also enables the Vocera Genie to say the actual correct time in voice prompts that users hear.

If you are planning to deploy a Vocera cluster, best practice is to synchronize the clocks on each server in the cluster. You are not required to synchronize the clocks to support cluster failover; however, if the clocks are set to different times, troubleshooting with system log files and analyzing Vocera Report Server log files becomes difficult after a failover.

If the servers physically reside in different time zones, you should set them all to a single time zone at the operating system level, then use Vocera to specify the actual time zone for each site.

To synchronize cluster server clocks:

  1. At the operating system level, set each server in the cluster to the same time zone.
    See your operating system documentation for additional information.
  2. Synchronize the clocks in every server in the cluster. For example, you can make sure the clocks are synchronized in one of the following ways:
    • Set the clock of each server in the cluster to sync to the same internet time source.
    • Use the Windows Time service to make sure that each server in the cluster uses a common time.
    See your operating system documentation for additional information.
  3. After Vocera Voice Server is installed, use the Sites screen to specify the time zone of every site. See the Vocera Voice Server Administration Console Guide for complete information.
