Use this command to set the system software clock.
clock set { hour [ :minute [ :second ] ] } [ month [ day [ year ] ] ]
hour [ :minute [ :second ] ]
Sets software time in the format of hour: minute: second. Only the specified
parameters (hour, minute, or second) can reset. The unspecified
parameters keep the current system values.
Sets month. The range is from 1 to 12.
Sets date. The range is from 1 to 31. If the day does not exist in the current
month, the date is calculated backward.
Sets year. The range is from 1970 to 2069.
1. The time parameter is mandatory. After setting time, set month, day, and year, which can be
neglected according to your needs. The parameter that is neglected keeps the current system value.
For example, if the current hardware time is "2012-02-29 09:33:44" and you want to change month
and hour and keep values of other parameters, use the clock set
12 5
command to change the
current time into "2012-05-29 12:33:44".
2. If the value of parameter day is between 1 and 31, but the current month does not contain that day,
the value will be calculated backward.
For example, February 2012 has 29 days. If you use the clock set
11:30
2 31 2012 command to set
the date to February 31, by default, the system adds two days backward. Therefore, the current
hardware time is "2012-03-02 11:30:23".
The following example changes the current software time of the system (for example, 2012-02-01
18:23:06) into 6 o’clock and keeps the values of other parameters.
