Setting the Time Zone and Daylight Saving Time Date Range

By default, the time zone is UTC and the daylight saving time date range is from 2:00 a.m. on the first
Sunday in April to 2:00 a.m. on the last Sunday in October. To change the time zone and daylight saving
time date range, perform the following steps:
To set the time zone, enter the following command in global configuration mode:
Step 1
hostname(config)# clock timezone zone [-] hours [ minutes ]
Where zone specifies the time zone as a string, for example, PST for Pacific Standard Time.
The [-]hours value sets the number of hours of offset from UTC. For example, PST is -8 hours.
The minutes value sets the number of minutes of offset from UTC.
To change the date range for daylight saving time from the default, enter one of the following commands.
Step 2
The default recurring date range is from 2:00 a.m. on the second Sunday in March to 2:00 a.m. on the
first Sunday in November.

To set the start and end dates for daylight saving time as a specific date in a specific year, enter the
following command:
hostname(config)# clock summer-time zone date { day month | month day } year hh : mm { day
month | month day } year hh : mm [ offset ]
If you use this command, you need to reset the dates every year.
The zone value specifies the time zone as a string, for example, PDT for Pacific Daylight Time.
The day value sets the day of the month, from 1 to 31. You can enter the day and month as April 1
or as 1 April, for example, depending on your standard date format.
The month value sets the month as a string. You can enter the day and month as April 1 or as 1 April,
for example, depending on your standard date format.
The year value sets the year using four digits, for example, 2004. The year range is 1993 to 2035.
The hh:mm value sets the hour and minutes in 24-hour time.
The offset value sets the number of minutes to change the time for daylight saving time. By default,
the value is 60 minutes.
To specify the start and end dates for daylight saving time, in the form of a day and time of the
month, and not a specific date in a year, enter the following command.
hostname(config)# clock summer-time zone recurring [ week weekday month hh : mm week
weekday month hh : mm ] [ offset ]
This command lets you set a recurring date range that you do not need to alter yearly.
The zone value specifies the time zone as a string, for example, PDT for Pacific Daylight Time.
The week value specifies the week of the month as an integer between 1 and 4 or as the words first
or last. For example, if the day might fall in the partial fifth week, then specify last.
