16.3.1 Pre - de fine d NTP Time Se rve rs 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.
Time Server Address Enter the IP address or URL of your time server. Check with your ISP/network administrator if
you are unsure of this information.
Sync. Now Click this button to have the Zyxel Device get the time and date from a time server (see the
Time Se rve r Ad d re ss field). This also saves your changes (except the daylight saving settings).
Time Zone Setup
Time Zone Choose the time zone of your location. This will set the time difference between your time
zone and Greenwich Mean Time (GMT).
Enable Daylight
Saving
Daylight saving is a period from late spring to 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.
Start Date Configure the day and time when Daylight Saving Time starts if you selected Ena ble Da ylig ht
Sa ving . The a t 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 Se c o nd, Sunda y, Ma rc h and type 2 in the a t
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 La st, Sunda y, Ma rc h. The time you
type in the a t 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 Ena b le Daylig ht
Sa ving . The a t 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, Sunda y, No ve m b e r and type 2 in the a t field.
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 La st, Sund a y, O c tob e r. The
time you type in the a t 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).
Offset Specify how much the clock changes when daylight saving begins and ends.
Enter a number from 1 to 5.5 (by 0.5 increments).
For example, if you set this field to 3.5, a log occurred at 6 P.M. in local official time will
appear as if it had occurred at 10:30 P.M.
Apply Click App ly to save your changes back to the Zyxel Device.
Reset Click Re se t to return the screen to its last-saved settings.
