System Time Commands
dst-zone
Syntax [no] dst-zone [std-zone-name | non-std-zone-name]
Context config>system>time
Description This command configures the start and end dates and offset for summer time or daylight savings time to
override system defaults or for user defined time zones.
When configured, the time is adjusted by adding the configured offset when summer time starts and
subtracting the configured offset when summer time ends.
If the time zone configured is listed in Table 21, System-defined Time Zones, on page 214, then the starting
and ending parameters and offset do not need to be configured with this command unless it is necessary to
override the system defaults. The command returns an error if the start and ending dates and times are not
available either in Table 21 on or entered as optional parameters in this command.
Up to five summer time zones may be configured, for example, for five successive years or for five different
time zones. Configuring a sixth entry will return an error message. If no summer (daylight savings) time is
supplied, it is assumed no summer time adjustment is required.
The no form of the command removes a configured summer (daylight savings) time entry.
Default none — No summer time is configured.
Parameters std-zone-name — The standard time zone name. The standard name must be a system-defined zone in
Table 21. For zone names in the table that have an implicit summer time setting, for example MDT for
Mountain Daylight Saving Time, the remaining start-date, end-date and offset parameters need to be
provided unless it is necessary to override the system defaults for the time zone.
Values std-zone-name ADT, AKDT, CDT, CEST, EDT, EEST, MDT, PDT, WEST
non-std-zone-name — The non-standard time zone name. Create a user-defined name created using the zone
command on page 368
Values 5 characters maximum
