Manage the Date and Time
An accurate date and time in the DMM assures accuracy for events listed in the System Log and
for traps and alarms sent to the system administrator, as well as for all events listed in event logs
for individual modules within the system. The date and time for the DMM overrides any date and
time set in another module in the domain.
You can choose either of two methods for setting the date and time, depending on your access to
an external network and your need for accuracy.
• For accuracy within a large network, you can set up the DMM to synchronize the system date
and time to an SNTP server. The SNTP date and time overrides the date and time set
anywhere else in the system. When the DMM contacts the SNTP server to synchronize the
time, the event appears in the System Log, whether or not the SNTP server responds.
• If you choose to not use SNTP to maintain the date and time, or do not have access to the
Internet and an SNTP server, you can set it directly at the DMM. In any case, the date and
time for the DMM overrides any date and time set in another module in the domain.
To set up synchronization with SNTP, follow these steps:
1. At the Domain Management Module menu, type 10 , "SNTP Configuration" and press
<Enter>.
2. At the SNTP Client Configuration screen, type the number for a parameter and press
<Enter>, then follow the prompts on the screen.
• Sntp Client UTP Offset (hours): Set the difference, in hours, between this DMM and
Coordinated Universal Time (UTC), which is similar to Greenwich Mean Time (GMT);
Range is -12 to 12
• Sntp Client Sync Interval (minutes): Set how often, in minutes, that the DMM tries to
synchronize its time to the Sntp server; Range is 0 (attempt to synchronize at DMM bootup,
only) to 1440 (once daily)
• Enter the values for primary and alternate SNTP servers:
• IP Address: Set the address for the server; 0.0.0.0 indicates no server
• Retries: How many times the DMM tries to synchronize before trying the alternate
server or giving up; Range is 0 to 10
• Timeout (seconds): How long between unsuccessful attempts; Range is 1 to 30
• Priority: Set which server to contact first; Range is 1 to 255 with higher priority for
lower numbers; if priority is the same for two servers, the DMM alternates tries between
the servers
3. To return to the Domain Management Module menu, press <Esc>.
To directly set the date and time, follow these steps:
1. At the Domain Management Module menu, type 9 , "Set Date and Time" and press <Enter>.
2. At the prompt to enter the current date and time, type the current information in
DD/MM/YYYY HH:MM format.
