Description
Use clock summer-time repeating to set a recurring daylight saving schedule.
Use undo clock summer-time to cancel the configuration of the daylight saving time.
By default, daylight saving time is disabled and UTC time zone applies.
The interval between start-time start-date and end-time end-date must be longer than one day and shorter
than one year. If the current system time is in the specified daylight saving days, the add-time value
automatically adds to the system time.
To verify the setting, use the display clock command.
The timestamps in system messages are adjusted in reference to the time zone and daylight saving
schedule.Related commands: clock datetime, clock summer-time one-off, clock timezone, and display
clock.
Examples
# Set the system time ahead one hour every year after (inclusive) for the period from August 1 at
06:00:00 to September 1 at 06:00:00.
