DESCRIPTION
This field displays the last updated date from the time server or the
last date configured manually.
When you set Time and Date Setup to Manual, enter the new date
in this field and then click Apply.
Select this radio button to have the ZyWALL get the time and date
from the time server you specify below. The ZyWALL requests time
and date settings from the time server under the following
circumstances.
• When the ZyWALL starts up.
• When you click Apply or Synchronize Now in this screen.
• 24-hour intervals after starting up.
Enter the IP address or URL of your time server. Check with your ISP/
network administrator if you are unsure of this information.
time server (see the Time Server Address field). This also saves
your changes (except the daylight saving settings).
Choose the time zone of your location. This will set the time difference
between your time zone and Greenwich Mean Time (GMT).
Daylight saving is a period from late spring to early fall when many
countries set their clocks ahead of normal local time by one hour to
give more daytime light in the evening.
Select this option if you use Daylight Saving Time.
Configure the day and time when Daylight Saving Time starts if you
selected Enable Daylight Saving. The at 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 type 2 in the at
field.
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 at 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).
