Get from Time 

Server

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

Address

Enter the IP address or URL (up to 20 extended ASCII characters in 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 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 first Sunday 

of April. 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 First, Sunday, April 

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).
