5.4.1. The Real Time Clock and Calendar
The Real Time Clock menu is used to set the RSM's internal clock and calendar. To
access the Real Time Clock Menu, proceed as follows:
Text Interface: Type /F and press [Enter]. The System Parameters menu will
appear as shown in Figure 5.3. At the System Parameters menu, type 3 and press
[Enter] to display the Real Time Clock menu.
Web Browser Interface: Click on the "System Properties" link at the left hand side
of the RSM Home Screen to display the System Parameters menu as shown in
Figure 5.4. From the System Parameters Menu, click on the "Real Time Clock" link
to access the Real Time Clock menu.
The configuration menu for the Real Time Clock offers the following options:
Date: Sets the Month, Date, Year and day of the week for the RSM’s real-time
clock/calendar.
Time: Sets the Hour, Minute and Second for the RSM’s real time clock/calendar.
Key in the time using the 24-hour (military) format.
Time Zone: Sets the time zone, relative to Greenwich Mean Time. Note that the
Time Zone setting will function differently, depending on whether or not the NTP
feature is enabled and properly configured. (Default = GMT (No DST).)
NTP Enabled: The Time Zone setting is used to adjust the Greenwich Mean
Time value (received from the NTP server) to determine the precise local time for
the selected time zone.
NTP Disabled: If NTP is disabled, or if the RSM is not able to access the NTP
server, then status screens and activity logs will list the selected Time Zone and
current Real Time Clock value, but will not apply the correction factor to the
displayed Real Time Clock value.
NTP Enable: When enabled, the RSM will contact an NTP server (defined via
the NTP IP Address prompts) once a day, and update its clock based on the NTP
server time and selected Time Zone. (Default = Off.)
Notes:
The RSM will also contact the NTP server and update the time whenever you
change NTP parameters.
To command the RSM to immediately contact the NTP server at any time,
make certain that the NTP feature is enabled and configured, then type /F
and press [Enter]. When the System Parameters menu appears, press
[Esc]. The RSM will save parameters and then attempt to contact the server,
as specified by currently defined NTP parameters.
Primary NTP Address: Defines the IP address or domain name (up to 64
characters long) for the primary NTP server. (Default = undefined.)
