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 26, System-defined Time Zones, on page 208, 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 26 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 26. 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 369
Values 5 characters maximum
