Administering the Switch
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
This example shows how to manually set the system clock to 1:32 p.m. on July 23, 2001:
Switch# 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:

Step 2

[minutes-offset]
Step 3

*—Time is not authoritative.
(blank)—Time is authoritative.
.—Time is authoritative, but NTP is not synchronized.
Purpose
Enter global configuration mode.
Set the time zone.
The switch keeps internal time in universal time coordinated (UTC), so
this command is used only for display purposes and when the time is
manually set.
Return to privileged EXEC mode.
•
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.
•
For year, specify the year (no abbreviation).
•
•
For zone, enter the name of the time zone to be displayed when
standard time is in effect. The default is UTC.
•
For hours-offset, enter the hours offset from UTC.
•
(Optional) For minutes-offset, enter the minutes offset from UTC.
