Setting the System Clock
If you have an outside source on the network that provides time services, such as an NTP server, you do
not need to manually set the system clock.
Beginning in privileged EXEC mode, follow these steps to set the system clock:
Command
Step 1
clock set hh:mm:ss day month year
or
clock set hh:mm:ss month day year
Step 2
show running-config
Step 3
copy running-config startup-config
This example shows how to manually set the system clock to 1:32 p.m. on July 23, 2001:
bridge# clock set 13:32:00 23 July 2001
Displaying the Time and Date Configuration
To display the time and date configuration, use the show clock [detail] privileged EXEC command.
The system clock keeps an authoritative flag that shows whether the time is authoritative (believed to be
accurate). If the system clock has been set by a timing source such as NTP, the flag is set. If the time is
not authoritative, it is used only for display purposes. Until the clock is authoritative and the
authoritative flag is set, the flag prevents peers from synchronizing to the clock when the peers' time is
invalid.
The symbol that precedes the show clock display has this meaning:

.—Time is authoritative, but NTP is not synchronized.
For hh:mm:ss, specify the time in hours (24-hour format), minutes,

and seconds. The time specified is relative to the configured time
zone.
•
For day, specify the day by date in the month.
For month, specify the month by name.
