settings do not affect it.

and then click Apply.

User Defined Time 

Server Address 

Select User Defined Time Server Address and 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 Savings

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  

Daylight Savings. 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).
