Setting the System Clock

The switch clock displays time by using a 24-hour clock format. It can also be set for use in any time
zone. Daylight Savings Time (DST) is supported for a number of standard time zones. DST parameters
can be programmed to support non-standard time zones and time off-set applications.
All switch files and directories listed in the flash directory bear a time stamp. This feature is useful for file
management purposes.

Setting Date and Time

You can set the local date, time zone, and time for your switch or you can also set the switch to run on
Universal Time Coordinate (UTC or GMT). If applicable, you can also configure Daylight Savings Time
(DST or Summertime) parameters.
Note. If you have multiple switches in a stack, you must set the date and time on both the primary and the
secondary switch. Otherwise, if you experience a fail-over situation, the secondary switch time and date
will not match. You can use the
set time and date. For more information on redundancy, refer to
Content."

new date in the command line, the switch will display the current system date.

Time Zone

To determine the current time zone or to specify a new time zone for your switch, use the

on UTC time (or Greenwich Mean Time). The following is displayed for the Pacific standard time zone:
