Usage guidelines
The UTC time, together with the local time zone and daylight saving time, determines the system time.
You can use the
display clock
command to view the system time.
A correct system time setting is essential to network management and communication. Set the system time
correctly or use NTP to synchronize your device with a trusted time source before you run it on the
network.
Examples
# Set the UTC time to 08:08:08 01/01/2012.
<Sysname> clock datetime 8:8:8 1/1/2012
# Set the UTC time to 08:10:00 01/01/2012.
<Sysname> clock datetime 8:10 2012/1/1
