Configuring Time and Date Manually
DETAILED STEPS
EXAMPLE
This example shows how to specify that DST starts on the first Sunday in April at 02:00 and ends on the
last Sunday in October at 02:00:
Switch(config)# clock summer-time PDT recurring 1 Sunday April 2:00 last Sunday October
2:00
Specific Dates for Daylight Saving Time
Follow this procedure if summer time in your area does not follow a recurring pattern (configure the
exact date and time of the next summer time events):
The first part of the clock summer-time global configuration command specifies when summer time
begins, and the second part specifies when it ends. All times are relative to the local time zone. The start
time is relative to standard time. The end time is relative to summer time. If the starting month is after
the ending month, the system assumes that you are in the southern hemisphere.
BEFORE YOU BEGIN
Obtain the daylight saving time information for your time zone.

Step 2
clock summer-time zone

Configure DST to start and end on the specified days every year.
DST is disabled by default. If you specify clock summer-time
zone recurring without parameters, the summer time rules
default to the United States rules.
• For zone, specify the name of the time zone (for example,
PDT) to be displayed when DST is in effect.
• (Optional) For week, specify the week of the month (1 to 5 or
last).
• (Optional) For day, specify the day of the week (Sunday,
Monday...).
• (Optional) For month, specify the month (January,
February...).
• (Optional) For hh:mm, specify the time (24-hour format) in
hours and minutes.

during DST. The default is 60.
