5.4.1 Pre-Defined NTP Time Servers List
The WiMAX Device uses a pre-defined list of NTP time servers if you do not specify
a time server or it cannot synchronize with the time server you specified. It can
use this list regardless of the time protocol you select.
When the WiMAX Device uses the list, it randomly selects one server and tries to
synchronize with it. If the synchronization fails, then it goes through the rest of
the list in order until either it is successful or all the pre-defined NTP time servers
have been tried.
Time Protocol Select the time service protocol that your time server
uses.Check with your ISP or network administrator, or use trial-
and-error to find a protocol that works.
Daytime (RFC 867) - This format is day/month/year/time
zone.
Time (RFC 868) - This format displays a 4-byte integer giving
the total number of seconds since 1970/1/1 at 0:0:0.
NTP (RFC 1305) - This format is similar to Time (RFC 868).
