LABEL

DESCRIPTION

Manual

Select this radio button to enter the time and date manually. If you configure a

 

new time and date, Time Zone and Daylight Saving at the same time, the new

 

time and date you entered has priority and the Time Zone and Daylight Saving

 

settings do not affect it.

 

When you enter the time settings manually, the ZyXEL Device uses the new

 

setting once you click Apply.

 

Note: If you enter time settings manually, they revert to their

 

defaults when power is lost.

 

 

New Time

This field displays the last updated time from the time server or the last time

(hh:mm:ss)

configured manually.

 

When you set Time and Date Setup to Manual, enter the new time in this field

 

and then click Apply.

New Date

This field displays the last updated date from the time server or the last date

(yyyy/mm/dd)

configured manually.

 

When you set Time and Date Setup to Manual, enter the new date in this field

 

and then click Apply.

Get from Time

Select this radio button to have the ZyXEL Device get the time and date from the

Server

time server you specified below.

 

 

Time Protocol

Select the time service protocol that your time server sends when you turn on the

 

ZyXEL Device. Not all time servers support all protocols, so you may have to

 

check with your ISP/network administrator or use trial and error to find a protocol

 

that works.

 

The main difference between them is the format.

 

Daytime (RFC 867) format is day/month/year/time zone of the server.

 

Time (RFC 868) format displays a 4-byte integer giving the total number of

 

seconds since 1970/1/1 at 0:0:0.

 

The default, NTP (RFC 1305), is similar to Time (RFC 868).

 

 

Time Server

Enter the IP address or URL (up to 20 extended ASCII characters in length) of

Address

your time server. Check with your ISP/network administrator if you are unsure of

 

this information.

 

 

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).

 

 

Daylight Saving

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.

 

 

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).
