45.3.1 Pre-defined NTP Time Servers List

When you turn on the ZyWALL for the first time, the date and time start at 2003-01-01

00:00:00. The ZyWALL then attempts to synchronize with one of the following pre-defined

list of Network Time Protocol (NTP) time servers.

The ZyWALL 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.

0.pool.ntp.org

1.pool.ntp.org

2.pool.ntp.org

When the ZyWALL 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 ZyWALL 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.

Click the Synchronize Now button to get the time and date from the time server you specified

in the Time Server Address field.

When the Please Wait... screen appears, you may have to wait up to one minute.

The Current Time and Current Date fields will display the appropriate settings if the

synchronization is successful.

If the synchronization was not successful, a log displays in the View Log screen. Try

reconfiguring the Date/Time screen.

To manually set the ZyWALL date and time.

1 Click System > Date/Time.

2 Select Manual under Time and Date Setup.

3 Enter the ZyWALL's time in the New Time field.

4 Enter the ZyWALL's date in the New Date field.

5 Under Time Zone Setup, select your Time Zone from the list.
