If you need to configure System Platform date and time settings manually instead of configuring the system to synchronize with a Network Time Protocol (NTP) server, you will first need to manually set the timezone in which the System Platform server resides.
The system displays the Date/Time Configuration page with default configuration settings.
Note On the main server, you need to select the time zone relevant to the server location. In the case of ESS or LSP, you must set up the time zone, which is the same as that of the main server. In a failover situation, the ESS or the LSP provide the correct time information to display on the phones with the help of the time zone and the translation information.
The system sets the selected time zone on the System Platform virtual machines (System Domain and Console Domain). The system also updates the time zone for other virtual machines running on the platform.
Configure date and time for the System Platform server. See Configuring the date and time for the System Platform server.
