Network Time 
Protocol
Select this option to use Network Time Protocol (NTP) for the time 
service.
NTP Server Select a pre-designated time server or type the IP address of your time 
server. The Switch searches for the timeserver for up to 60 seconds.
Time Zone  Select the time difference between UTC (Universal Time Coordinated, 
formerly known as GMT, Greenwich Mean Time) and your time zone from 
the drop-down list box. 
Daylight Saving Settings
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.
State Select Enable if you want to use Daylight Saving Time. Otherwise, 
select Disable to turn it off.
Start Date Configure the day and time when Daylight Saving Time starts if you 
enabled Daylight Saving Time. The time is displayed in 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 and the last 
field depends on your time zone. In Germany for instance, you would 
select 2:00 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 
enabled Daylight Saving Time. The time 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 First, 
Sunday, November and 2:00.
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 and the last 
field depends on your time zone. In Germany for instance, you would 
select 2:00 because Germany's time zone is one hour ahead of GMT or 
UTC (GMT+1).
