Basic Configuration
5.3.1. The Real Time Clock and Calendar
The Real Time Clock menu is used to set the RPS 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 for the real-time clock/calendar.
•
Time:
Sets the Hour, Minute and Second for the RPS 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 upon 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) in order to determine the precise local time for
the selected time zone.
NTP Disabled:
If NTP is disabled, or if the RPS 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 RPS 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.)
Notes:
• The RPS will also contact the NTP server and update the time whenever you
change NTP parameters.
• To cause RPS 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 RPS 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.)
Note:
In order to use domain names for web addresses, DNS parameters must first
be defined as described in Section 5.9.5.
•
Secondary NTP Address:
Defines the IP address or domain name (up to 64 characters
long) for the secondary, fallback NTP Server. (Default = undefined.)
Note:
In order to use domain names for web addresses, DNS parameters must be
defined as described in Section 5.9.5.
