Configuring Time and Date Manually
EXAMPLE
This example shows how to manually set the system clock to 1:32 p.m. on July 23, 2014:
Switch# clock set 13:32:00 23 July 2014
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 not authoritative.
• (blank)—Time is authoritative.
• .—Time is authoritative, but NTP is not synchronized.
