Commands
1.1 Basic System Configuration and Management
Commands
1.1.1 clock datetime
Syntax
clock datetime HH:MM:SS YYYY/MM/DD
View
User view
Parameters
HH:MM:SS: Current time. HH ranges from 0 to 23. MM and SS range from 0 to 59.
YYYY/MM/DD: Year, month and date. YYYY ranges from 2000 to 2100. MM ranges
from 1 to 12 and DD ranges from 1 to 31.
Description
Use the clock datetime command to configure the current date and clock of the switch.
By default, the date and clock of the switch is set to 0:0:0, 2000/1/1.
The current date and clock of the switch must be set by this command where absolute
time is strictly required.
Related commands: display clock.
Examples
# Set the current date of the switch to 0:0:0, 2001/01/01.
<H3C> clock datetime 0:0:0 2001/01/01
1.1.2 clock summer-time
Syntax
clock summer-time zone-name { one-off | repeating } start-time start-date end-time
end-date offset-time

Parameters
zone-name: Name of the summer time, which is a string of 1 to 32 characters.
one-off: Sets the summer time of a certain year.
repeating: Sets the summer time of every year starting from a certain year.
start-time: Sets start time of the summer time, in the form of HH:MM:SS
(hour/minute/second).
start-date: Sets start date of the summer time, in the form of YYYY/MM/DD
(year/month/day).
end-time: Sets end time of the summer time, in the form of HH:MM:SS
(hour/minute/second).
end-date: Sets end date of the summer time, in the form of YYYY/MM/DD
(year/month/day).
offset-time: Sets the offset relative to the summer time, in the form of HH:MM:SS
(hour/minute/second).
Description
Use the clock summer-time command to set the name, start and end time of the
summer time.
Use the undo clock summer-time command to restore the local time to the default
UTC time.
After the configuration takes effect, the display clock command can be used to check
it. Besides, the time of the log or debugging information uses the local time after the
adjustment of the time zone and summer time.
Related commands: clock timezone.
Examples
# Set the summer time for z2 that starts at 06:00:00 on 08/06/2002 and ends at
06:00:00 on 01/09/2002 with the time adding 1 hour.

01:00:00
# Set the summer time for z2 that starts at 06:00:00 on 08/06 and ends at 06:00:00 on
01/09 in each year from 2002 on with the time adding 1 hour.

Description
Use the clock timezone command to set the information of the local time zone.
Use the undo clock timezone command to restore to the default Universal Time
Coordinated (UTC) time zone.
After the configuration takes effect, the display clock command can be used to check
it. Besides, the time of the log or debug information uses the local time after the
adjustment of the time zone and summer time.
Related commands: clock summer-time.
