Chapter 6 Administering the Switch Managing the System Time and Date Displaying the NTP Configuration You can use two privileged EXEC commands to display NTP information: • show ntp associations [detail] • show ntp status Note For detailed information about the fields in these displays, see the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 from the Cisco.com page under Documentation > Cisco IOS Software > 12.2 Mainline > Command References. Configuring Time and Date Manually If no other source of time is available, you can manually configure the time and date after the system is restarted. The time remains accurate until the next system restart. We recommend that you use manual configuration only as a last resort. If you have an outside source to which the switch can synchronize, you do not need to manually set the system clock. These sections contain this configuration information: • Setting the System Clock, page 6-11 • Displaying the Time and Date Configuration, page 6-12 • Configuring the Time Zone, page 6-12 • Configuring Summer Time (Daylight Saving Time), page 6-13 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: Step 1 Command clock set hh:mm:ss day month year or clock set hh:mm:ss month day year Purpose Manually set the system clock using one of these formats. • 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). 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 OL-8603-04 Catalyst 2960 Switch Software Configuration Guide 6-11
