Administration > General Settings > Setup > Date/Time
The Date/Time tab indicates the time zone and Network Time Protocol (NTP) settings for one or more appliances selected in the appliance tree. It can also indicate time discrepancies between your devices (appliances, the Orchestrator Server, and your browser). If the dates and times of devices are not synchronized, charts and report statistics will have varying timestamps for the same data.
Time differences shown for Orchestrator and your browser (client machine) are relative to the respective appliances. Appliance times should be within a minute of Orchestrator and browser times. If exceeded, an appliance alarm is issued.
TIP: To synchronize times, it is recommended that you configure the appliance, the Orchestrator server, and your client machine to use an NTP (Network Time Protocol) server.
To configure a synchronized date and time for an appliance, click the edit icon in the row associated with the appliance. The Date/Time Settings dialog box opens.
Use the Date/Time Settings dialog box to configure a synchronized date and time across your appliances, Orchestrator, and browser (client machine).
Select the appropriate time zone for your network from the Time zone drop-down list.
Select one of the following time/date configuration options:
Manual – Set the Date and Time fields manually.
NTP Time Synchronization – To specify an NTP server for automatic time/date synchronization, click Add. A grid row is created. In the Server field, type the URL for the NTP server to use. In the Version field, select the NTP version to use (version 3 or 4).
NOTE: It is generally recommended that you specify two or more NTP servers for timekeeping accuracy and reliability.
