Configuring Summer Time (Daylight Saving Time)
Purpose
Configures summer time to start and end on
specified days every year.
Configures summer time to start and end on the
specified days every year. 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.
Summer time is disabled by default. If you
specify clock summer-time zone recurring
without parameters, the summer time rules
default to the United States rules.
If the starting month is after the ending month,
the system assumes that you are in the southern
hemisphere.
