Configuring Date and Time Service

If you have used the Setup Wizard, you might have already configured the system date and time settings; the System Date and Time screen allows you to modify these settings.

Configure date, time, and NTP server designations on the System Date and Time screen.

Network Time Protocol (NTP) is a protocol that is used to synchronize computer clock times in a network of computers. Setting the correct system time and time zone ensures that the date and time recorded in the STM logs and reports are accurate. Changing the time zone requires the STM to restart to apply the updated settings.
