Clock Commands on Cisco IOS XR Software
C i s c o C o n f i d e n t i a l - B e t a R e v i e w R 3 . 7. 1
Use the clock summer-time command if you want the system to switch automatically to summer time
(for display only):
•
•
In both forms of the command, the first part of the command specifies when summer time begins, and
the second part specifies when it ends. All times are relative to the local time zone. The start time is
relative to standard time. The end time is relative to summer time. If the starting month is after the ending
month, the system assumes that you are in the Southern Hemisphere.

Examples The following example specifies that summer time starts on the first Sunday in April at 02:00 and ends
on the last Sunday in October at 02:00. The recurring keyword indicates that the rules apply every year.
RP/0/RP0/CPU0:router(config)# clock summer-time PDT recurring 1 Sunday April 2:00 last
Sunday October 2:00
If you live where summer time does not follow the pattern in the first example, you could set it to start
on October 12, 2005 at 02:00 and end on April 26, 2006 at 02:00, with the following example. The date
keyword indicates that the rules apply for the current year only.
RP/0/RP0/CPU0:router(config)# clock summer-time PDT date 12 October 2005 2:00 26 April
2006 2:00

Use the recurring form of the command to apply the rules on the configured day each year. If clock
summer-time zone recurring is specified without parameters, the summer time rules default to
United States standards. The default for the offset argument is 60 minutes.
Use the date form to specify a start and end date for summer time if you cannot use the first form.
