Managing the System Time and Date
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:

Configuring the Time Zone
Beginning in privileged EXEC mode, follow these steps to manually configure the time zone:
Command
Step 1
configure terminal
Step 2
clock timezone zone hours-offset
[minutes-offset]
Step 3
end
Step 4
show running-config
Step 5
copy running-config startup-config
The minutes-offset variable in the clock timezone global configuration command is available for those
cases where a local time zone is a percentage of an hour different from UTC. For example, the time zone
for some sections of Atlantic Canada (AST) is UTC-3.5, where the 3 means 3 hours and .5 means 50
percent. In this case, the necessary command is clock timezone AST -3 30.
To set the time to UTC, use the no clock timezone global configuration command.

*—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.
Verify your entries.
(Optional) Save your entries in the configuration file.
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.
