32.5 Pre-defined NTP Time Server Pools
When you turn on the ZyWALL for the first time, the date and time start at 2000-01-01
00:00:00. The ZyWALL then attempts to synchronize with an NTP time server from one of
the 0.pool.ntp.org, 1.pool.ntp.org or 2.pool.ntp.org NTP time server pools. These are virtual
clusters of time servers that use a round robin method to provide different NTP servers to
clients.
The ZyWALL continues to use the NTP time server pools if you do not specify a time server
or it cannot synchronize with the time server you specified.
"
The ZyWALL can use the NTP time server pools regardless of the time
protocol you select.
When the ZyWALL uses the NTP time server pools, it randomly selects one pool and tries to
synchronize with a server in 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 server pools have been tried.
Start Date
Configure the day and time when Daylight Saving Time starts if you selected
Enable Daylight Saving
. The
o'clock
field uses the 24 hour format. Here are a
couple of examples:
Daylight Saving Time starts in most parts of the United States on the second
Sunday of March. Each time zone in the United States starts using Daylight
Saving Time at 2 A.M. local time. So in the United States you would select
Second
,
Sunday
,
March
and
2:00
.
Daylight Saving Time starts in the European Union on the last Sunday of March.
All of the time zones in the European Union start using Daylight Saving Time at
the same moment (1 A.M. GMT or UTC). So in the European Union you would
select
Last
,
Sunday
,
March
. The time you type in the
o'clock
field depends on
your time zone. In Germany for instance, you would type 2 because Germany's
time zone is one hour ahead of GMT or UTC (GMT+1).
End Date
Configure the day and time when Daylight Saving Time ends if you selected
Enable Daylight Saving
. The
o'clock
field uses the 24 hour format. Here are a
couple of examples:
Daylight Saving Time ends in the United States on the first Sunday of November.
Each time zone in the United States stops using Daylight Saving Time at 2 A.M.
local time. So in the United States you would select
First
,
Sunday
,
November
and
2:00
.
Daylight Saving Time ends in the European Union on the last Sunday of
October. All of the time zones in the European Union stop using Daylight Saving
Time at the same moment (1 A.M. GMT or UTC). So in the European Union you
would select

October
. The time you type in the
o'clock
field
depends on your time zone. In Germany for instance, you would type 2 because
Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
