Set the Current Date and Time

To set the current date and time on the router, use the set date command:

 user@host> set date YYYYMMDDhhmm.ss 
 

YYYY is the four-digit year, MM is the two-digit month, DD is the two digit date, hh is the two-digit hour, mm is the two-digit minute, and ss is the two-digit second. At a minimum, you must specify the two-digit minute. All other parts of the date and time are optional.

To set the time zone, see Set the Time Zone. To configure time synchronization, see Configure the Network Time Protocol.

If you change the system clock on a router using the set date command, routing adjacencies might drop temporarily.
