Figure 8-6.SNTP time server enabled
The default for the SNTP server is disabled. If the customer chooses to use the SNTP feature,
then the state should be changed to enable and a server address input in the SNTP SERVER
field to indicate the source of the timing stream. The update interval must also be set to
indicate how often the IMACS should synchronize to the timing source. This field can be set
to adjust the timing any of 1, 3, 6, 12 and 24 hours. The UTC offset also should be set to
indicate the time offset from Greenwich Mean Time - anywhere from +13 to -12 hours. The
final field to be set is the DST offset, which is used to either disable Daylight Savings Time,
or alter it by an increment of 30 minutes, or one hour to two hours.
To set the current date and time for the Integrated Access System and allow the system to track
on its internal clock, press “t” in the SNTP Main Screen to choose the Time action from the
bottom line of that screen. The current date and time now appear in the lower left of the screen,
in the format MM-DD-YY HH-MM. The MM field (month) is highlighted.
Use the up-arrow and down-arrow keys to set the current month (01 to 12, as required). Also
move to each remaining field with the right-arrow and left-arrow keys, and select the current
day (DD) and year (YY), and the current hour (HH) and minute (MM). The current time of
day is displayed in 24-hour continuous format, where HH is 00 to 11 for a.m. and 12 to 23 for
p.m.
When you finish setting these fields, press <Enter> and then press “y” to confirm that you
want to save the changes. The system will subsequently stamp the current date and time on all
alarm messages it reports.
