Cisco SCE 8000 CLI Command Reference

Chapter 2 CLI Command Reference

clock summertime

Command Modes Global configuration

Command History This table includes the following release-specific history entries:

Usage Guidelines The format of the command varies somewhat, depending on how the dates for the beginning and end of

daylight saving time are determined for the particular location:

• If daylight saving time always begins and ends on the same day every year (recurring, as in the

United States):

–

Use the clock summertime recurring command.

–

Do not specify the year keyword.

• If the start and end of daylight saving time is different every year (not recurring, as in Israel):

–

Use the clock summertime command.

–

Specify the year keyword.

Authorization: admin

General Guidelines

The following guidelines apply to configuring daylight saving time transitions:

• Specify the time-zone code for daylight saving time.

• For recurring configurations, specify a day of the month (week number/first|last/day of the

week/month).

• For nonrecurring configurations, specify a date (month/day of the month/year).

• Define two days:

–

day1 is the beginning of daylight saving time.

–

day2 is the end of daylight saving time.

• In the Southern hemisphere, month2 must be earlier than month1, because daylight saving time

begins in the fall and ends in the spring.

• Specify the exact time that the transition should occur (24-hour clock):

–

Time of transition into daylight saving time, according to local standard time

–

Time of transition out of daylight saving time, according to local daylight saving time

Recurring Configurations

For the clock summertime recurring command, the default values are the United States transition rules:

• Daylight saving time begins at 2:00 (a.m.) on the second Sunday of March.

• Daylight saving time ends at 2:00 (a.m.) on the first Sunday of November.

Use the recurring keyword if daylight saving time always begins and ends on the same day every year.
