 in a file that (usually) uses the system model name with a “*.bin” 

extension, e.g., “Router.bin”. The upload process uses HTTP (Hypertext Transfer Protocol) and may 
take up to two minutes. After a successful upload, the system will reboot.

Get from Time 
Server

Select this radio button to have the Router get the time and date from the time server 
you specified below.

Auto

Select Auto to have the Router automatically search for an available time server and 
synchronize the date and time with the time server after you 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). 

End Date

Configure the day and time when Daylight Saving Time ends if you selected Daylight 
Savings. The o'clock field uses the 24 hour format. Here are a couple of examples:

Daylight Saving Time ends in the United States on the last Sunday of October. 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 Last, Sunday, October and type 2 in the o'clock 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 Last, Sunday, 
October. 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).
