Usage guidelines
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.
Examples
# Set the system time ahead one hour for the period between 06:00:00 on 08/01/2011 and 06:00:00
on 09/01/2011.
