Network Time Protocol (NTP)
The clock supplies accurate date and time information to the system. It can be set to run with or without a
connection to a network time server (NTP). It can be configured to display local time by setting the time zone and
daylight saving in the Time web page.
If an NTP server connection is available, the clock can be set to synchronize with the server time at regular
intervals.
PMP 450 devices may receive NTP data from a CMM3 or CMM4 module, an NTP server configured in the
system’s management network or a UGPS module.
The Time Zone option is configurable on the AP’s Time Configuration page, and may be used to offset the received
NTP time to match the operator’s local time zone. When set on the AP, the offset will be set for the entire sector
(SMs will be notified of the current Time Zone upon initial registration). If a Time Zone change is applied, the
SMs will be notified of the change in a best effort fashion, meaning some SMs may not pick up the change until the
next re-registration. Time Zone changes are noted in the Event Log of the AP and SM.
An AP which is receiving NTP date and time information from an NTP server or from a GPS synchronization
source may be used as an NTP server. Any client which has IP connectivity to the AP may request NTP date and
time information from the AP. No additional configuration (other than the AP receiving valid NTP data) is required
to use the AP as an NTP server.
