Removing the Current Time Zone Setting

From the SCE(config)# prompt, type no clock timezone and press Enter.

Step 1

Removes the timezone configuration and resets the timezone to the default value (UTC).

Configuring Daylight Saving Time

The SCE platform can be configured to automatically switch to daylight saving time on a specified date,
and also to switch back to standard time. In addition, the time zone code can be configured to vary with
daylight saving time if required. (For instance, in the eastern United States, standard time is designated
EST, and daylight saving time is designated EDT).

Options

The transition times into and out of daylight saving time may be configured in one of two ways,
depending on how the dates for the beginning and end of daylight saving time are determined for the
particular location:

Note
The day on which the transition takes place may be defined in several ways:

recurring — If daylight saving time always begins and ends on the same day every year, (as in the
United States), the clock summer-time recurring command is used. The beginning and ending days
for daylight saving time can be configured once, and the system will automatically perform the
switch every year.
not recurring — If the start and end of daylight saving time is different every year, (as in Israel), the
clock summer-time command is used. In this case, the transitions must be configured every year
for that particular year.
The "year" is not necessarily a calendar year. If the transition days are determined in the fall, the
transitions for that fall and the next spring may be configured.
Specific date — For example, March 29, 2004. A specific date, including the year, is defined for a
not recurring configuration.
First/last occurrence of a day of the week in a specified month — For example, the last Sunday in
March. This is used for a recurring configuration.
Day of the week in a specific week in a specified month — For example, Sunday of the fourth week
of March. (This would be different from the last Sunday of the month whenever there were five
Sundays in the month). This is used for a recurring configuration.
