The config>system>time>dst-zone context 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.
Use the following CLI syntax to configure summer time conditions.
config>system>time
dst-zone zone-name
end {end-week} {end-day} {end-month} [hours-minutes]
offset offset
start {start-week} {start-day} {start-month} [hours-minutes]

config>system>time>dst-zone# offset 0If the time zone configured is listed in Table: System-defined time zones , the starting and ending parameters and offset do not need to be configured with this command unless there is a need to override the system defaults. The command returns an error if the start and ending dates and times are not available either in Table: System-defined time zones or entered as optional parameters in this command.
