How to Perform Switch Administration

Configuring the Time Zone

The minutes-offset variable in the clock timezone global configuration command is available for those cases where a
local time zone is a percentage of an hour different from UTC. For example, the time zone for some sections of Atlantic
Canada (AST) is UTC-3.5, where the 3 means 3 hours and .5 means 50 percent. In this case, the necessary command
is clock timezone AST -3 30.
Command
1. configure terminal
2. clock timezone zone hours-offset
[minutes-offset]
3. end
Configuring Summer Time (Daylight Saving Time)
To configure summer time (daylight saving time) in areas where it starts and ends on a particular day of the week each
year, perform this task:
Command
1. configure terminal
2. clock summer-time zone recurring
[week day month hh:mm week day
month hh:mm [offset]]
3. end
Purpose
Enters global configuration mode.
Sets the time zone.
The switch keeps internal time in universal time coordinated (UTC), so this
command is used only for display purposes and when the time is
manually set.

zone—Enters the name of the time zone to be displayed when
standard time is in effect. The default is UTC.

hours-offset—Enters the hours offset from UTC.

(Optional) minutes-offset—Enters the minutes offset from UTC.
Returns to privileged EXEC mode.
Purpose
Enters global configuration mode.
Configures summer time to start and end on the specified days every
year.
Summer time is disabled by default. If you specify clock summer-time
zone recurring without parameters, the summer time rules default to the
United States rules.

zone—Specifies the name of the time zone (for example, PDT) to be
displayed when summer time is in effect.

(Optional) week—Specifies the week of the month (1 to 5 or last).

(Optional) day—Specifies the day of the week (Sunday, Monday...).

(Optional) month—Specifies the month (January, February...).

(Optional) hh:mm—Specifies the time (24-hour format) in hours and
minutes.

(Optional) offset—Specifies the number of minutes to add during
summer time. The default is 60.
Returns to privileged EXEC mode.
