Command Usage
◆ In some countries or regions, clocks are adjusted through the summer months
so that afternoons have more daylight and mornings have less. This is known as
Summer Time, or Daylight Savings Time (DST). Typically, clocks are adjusted
forward one hour at the start of spring and then adjusted backward in autumn.
◆ This command sets the summer-time time zone relative to the currently
configured time zone. To display a time corresponding to your local time when
summer time is in effect, you must indicate the number of minutes your
summer-time zone deviates from your regular time zone (that is, the offset).
Example
The following example sets a recurring 60 minute offset summer-time to begin on
the Friday of the 1st week of March at 01:59 hours and summer time to end on the
Saturday of the 2nd week of November at 01:59 hours.
Console(config)#clock summer-time MESZ recurring 1 friday march 01 59 2
saturday november 1 59 60
