Usage Guideline
Generally, if the system is synchronized by a valid outside timing mechanism, such as SNTP, there is
mp need to set the software clock. Use this command if no other time sources are available. The time
specified in this command is assumed to be in the time zone specified by the configuration of the
clock timezone command. The clock configured by this command will be applied to RTC if it is
available. The configured clock will not be stored in the configuration file.
If the clock is manually set and the SNTP server is configured, the system will still try to sync the clock
with the server. If the clock is manually set, but a new clock time is obtained by the SNTP server, the
clock will be replaced by the new synced clock.
Example
This example shows how to manually set the software clock to 6:00 p.m. on Jul 4, 2014.
Switch# clock set 18:00:00 4 Jul 2014
