17.4.1 Pre-defined NTP Time Servers List
When you turn on the Zyxel Device for the first time, the date and time start at 2003-01-01 00:00:00. The
Zyxel Device then attempts to synchronize with one of the following pre-defined list of Network Time
Protocol (NTP) time servers.
The Zyxel Device continues to use the following 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.
Table 78 Default Time Servers
0.pool.ntp.org
1.pool.ntp.org
2.pool.ntp.org
When the Zyxel Device uses the pre-defined list of NTP time servers, it randomly selects one server and
tries to synchronize with it. If the synchronization fails, then the Zyxel Device goes through the rest of the
list in order from the first one tried until either it is successful or all the pre-defined NTP time servers have
been tried.
