Chapter 5 The Setup Screens Table 17 SETUP > DHCP Client (continued) LABEL DESCRIPTION Time Protocol Select the time service protocol that your time server uses.Check with your ISP or network administrator, or use trialand-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. Time Server Address Time Zone Setup Time Zone Daylight Savings Start Date End Date Apply Reset NTP (RFC 1305) - This format is similar to Time (RFC 868). Enter the IP address or URL of your time server. Check with your ISP or network administrator if you are unsure of this information. Select the time zone at your location. Select this if your location uses daylight savings time. Daylight savings is a period from late spring to early fall when many places set their clocks ahead of normal local time by one hour to give more daytime light in the evening. Enter which hour on which day of which week of which month daylight-savings time starts. Enter which hour on the which day of which week of which month daylight-savings time ends. Click to save your changes. Click to restore your previously saved settings. 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.

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).
Time Server
Address
Enter the IP address or URL of your time server. Check with your
ISP or network administrator if you are unsure of this
information.
Time Zone Setup
Time Zone

savings is a period from late spring to early fall when many
places set their clocks ahead of normal local time by one hour to
give more daytime light in the evening.
Start Date
Enter which hour on which day of which week of which month
daylight-savings time starts.
End Date
Enter which hour on the which day of which week of which
month daylight-savings time ends.
