Configuring the System Clock
This section explains how to display and manually set the system clock. It contains the following topics:
• Displaying the System Clock, page 17-27
• Manually Setting the System Clock, page 17-28
Displaying the System Clock
Use the show clock [detail] command to display the system clock. You can use the detail option to
indicate the clock source (NTP or system) and the current summertime setting (if any). The system clock
keeps an authoritative flag that indicates 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.
Table 17-3 lists the system clock flags.
To display the system clock, follow these steps:
Step 1 Log in to the CLI.
Step 2 Display the system clock.
