Description
Use the clock summer-time repeating command to adopt the daylight saving time repeatedly.
Use the undo clock summer-time command to cancel the configuration of the daylight saving time.
For example, if you specify start-date and start-time as 2008/6/6 and 00:00:00, end-date and
end-time to 2008/10/01 and 00:00:00, and add-time to 01:00:00, the daylight saving time range is
from 00:00:00 of June 6 to 00:00:00 of October 1 each year from 2008 (2008 inclusive). The daylight
saving time adds one hour to the standard time of the firewall.
NOTE:
• To view the result after the configuration takes effect, use the display clock command. The time
displayed in the log or debug information is the adjusted local time.
• The time range from “start-time” in “start-date” to “end-time” in “end-date” must be lon
g
er than one da
y
and shorter than one year. Otherwise, the ar
g
ument is considered as invalid and the confi
g
uration fails.
• If the standard time of the firewall is in the time range specified with this command, the system time
automatically adds “add-time” after the execution of this command.
Related commands: clock datetime, clock summer-time one-off, clock timezone, and display clock.
