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.

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.

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.
