2408 CHAPTER 162: BASIC CONFIGURATION COMMANDS
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 device 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.
Note that:
■ 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.
Related command: clock datetime, clock summer-time one-off, clock timezone, display clock.
Example # For the summer time in abc2 between 06:00:00 on 08/01/2007 and 06:00:00
on 09/01/2007 and from 06:00:00 08/01 to 06:00:00 on 09/01 each year after
2007, set the system clock ahead one hour.
