Usage guidelines
CAUTION:
This command changes the system time, which affects the execution of system time-related
features (for example, scheduled tasks) and collaborative operations of the device with other
devices (for example, log reporting and statistics collection). Before executing this command, make
sure you fully understand its impact on your live network.
Correct system time is essential to network management and communication. You must configure
the system time correctly before you run the device on the network.
For the device to use the local system time, execute the
clock protocol none
command and
this command in turn. The specified system time takes effect immediately. Then, the device uses the
clock signals generated by its built-in crystal oscillator to maintain the system time.
A device power cycling operation restores the local system time to the default. After the device is
power cycled, you must execute this command again to set the local system time.
Examples
# Set the system time to 08:08:08 01/01/2015.
<Sysname> clock datetime 8:8:8 1/1/2015
# Set the system time to 08:10:00 01/01/2015.
<Sysname> clock datetime 8:10 2015/1/1
