Configuration>System>Time/Date
When Configuration>System Time/Date is selected in Expert mode, the screen in Web Manager Configuration>System Menu Options appears.
An administrative user can use the Time/Date screen to configure the timezone and the OnSite’s time and date in one of the following two ways:
Enabling Network Time Protocol (NTP) and configuring the IP address of an NTP server synchronizes the OnSite’s system clock with the NTP server, which maintains the true time (the average of many high-accuracy clocks around the world).
If “Disable” is selected from the Network Time Protocol menu, manual configuration includes configuring the timezone and manually entering the date and time.
Configuring the timezone is done in either one of the two ways listed in the following list.
See Custom Editing the Time Zone.
See Selecting From the Timezone Menu.
When the Time/Date option is selected, if “Old Style” is selected on the “Timezone” menu, the following window appears.
