Description
Use the clock summer-time repeating command to adopt summer-time repeatedly.
Use the undo clock summer-time command to cancel the configuration of the
daylight saving time.
By default, daylight saving time is configured on the AC, and the UTC time zone is
applied.
For example, when start-date and start-time are set to 2007/6/6 and 00:00:00, end-date
and end-time to 2007/10/01 and 00:00:00, and add-time to 01:00:00, it specifies to
adopt daylight saving time from 00:00:00 of June 6 until 00:00:00 of October 1 each
year from 2007 (2007 inclusive). The daylight saving time adds one hour to the current
AC time.
After the configuration takes effect, use the display clock command to view the result.
The information such as log file and debug adopts the local time modified by time-
zone and daylight saving time.
The time range from "start-time" in "start-date" to "end-time" in "end-date" must be
longer than one day and shorter than one year. Otherwise, the argument is considered
as invalid and the configuration fails.

If the current system time is in the time range specified with this command, the
system time automatically adds "add-time" after the execution of this command.
