DESCRIPTION

 

 

New Time

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

 

 

(hh:mm:ss)

time 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

 

 

(yyyy/mm/dd)

date 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

 

 

Server

from the 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

 

 

Address

length) of 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

Daylight saving is a period from late spring to early fall when many

 

 

Savings

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 type 2 in the o'clock

 

 

 

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 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).
