How to Perform Switch Administration
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 Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
clock timezone zone hours-offset
[minutes-offset]
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.
Step 3
end Returns to privileged EXEC mode.
Command Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
clock summer-time zone recurring
[week day month hh:mm week day month
hh:mm [offset]]
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.
Step 3
end Returns to privileged EXEC mode.
