Summer Time Conditions
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 will be adjusted by adding the configured offset when summer
time starts and subtracting the configured offset when summer time ends.
CLI Syntax: 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]
Example: config>system# time
config>system>time# dst-zone pt
config>system>time>dst-zone# start second sunday april
02:00
end first sunday october 02:00
config>system>time>dst-zone# offset 0
If the time zone configured is listed in Table 39, then 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 will return an error if the start and ending dates and times are
not available either in Table 39 or entered as optional parameters in this command.
The following example displays the configured parameters.
