Start Date (mm-
nth-week-hr)
Configure the day and time when Daylight Saving Time starts if you selected Yes 
in the Daylight Saving field. The hr 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 Mar.2ndSun.  
and type 02 in the hr 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  
Mar.LastSun. The time you type in the hr field depends on your time zone. In 
Germany for instance, you would type 02 because Germany's time zone is one 
hour ahead of GMT or UTC (GMT+1). 
End Date (mm-
nth-week-hr)
Configure the day and time when Daylight Saving Time ends if you selected Yes in 
the Daylight Saving field. The hr field uses the 24 hour format. Here are a couple 
of examples:
Daylight Saving Time ends in the United States on the first Sunday of November. 
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 Nov.FirstSun. and type 02 
in the hr 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 
Oct.LastSun. The time you type in the hr field depends on your time zone. In 
Germany for instance, you would type 02 because Germany's time zone is one 
hour ahead of GMT or UTC (GMT+1). 
Once you have filled in this menu, press [ENTER] at the message “Press ENTER to Confirm or ESC to
