Basic Configuration
5.3.1. The Real Time Clock and Calendar
The Real Time Clock menu is used to set the TSM/RSM's internal clock and calendar.
The configuration menu for the Real Time Clock offers the following options:
• Date: Sets the Month, Date, Year and day of the week.
• Time: Sets the Hour, Minute and Second for the TSM/RSM’s real time clock/
calendar. Key in the time using the 24-hour (military) format.
• TimeZone: Sets the time zone, relative to Greenwich Mean Time. Note that the
Time Zone setting will function differently, depending upon whether or not the NTP
feature is enabled and properly configured. (Default = GMT (No DST))
NTPEnabled: The Time Zone setting is used to adjust the Greenwich Mean
Time value (received from the NTP server) in order to determine the precise local
time for the selected time zone.
NTPDisabled: If disabled, or if the unit cannot access the NTP server, then
status screens and activity logs will list the selected Time Zone and Real Time
Clock value, but will not apply the correction factor to the Real Time Clock value.
• NTPEnable: When enabled, the TSM/RSM will contact an NTP server (defined
via the NTP Address prompts) once a day, and update its clock based on the NTP
server time and selected Time Zone. (Default = Off)
