DETAILED STEPS
The first part of the
clock summer-time
global configuration 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.
To disable summer time, use the
no clock summer-time
command in global configuration mode.
This example shows how to set summer time to start on October 12, 2000, at 02:00, and end on April 26,
2001, at 02:00:
AP(config)#
clock summer-time pdt date 12 October 2000 2:00 26 April 2001 2:00
