This command sets the time zone and/or time zone offset for the device.
The SR-series router OS supports system-defined and user-defined time zones. The system-defined time zones are listed in the Time Zones section.
For user-defined time zones, the zone and the UTC offset must be specified.
The no form of the command reverts to the default of Coordinated Universal Time (UTC). If the time zone in use was a user-defined time zone, the time zone will be deleted. If a dst-zone command has been configured that references the zone, the summer commands must be deleted before the zone can be reset to UTC.
zone UTC 00
For system-defined time zones, a different offset cannot be specified. If a new time zone is needed with a different offset, the user must create a new time zone. Note that some system-defined time zones have implicit summer time settings which causes the switchover to summer time to occur automatically; configuring the config>system>time dst-zone command is not required.
A user-defined time zone name is case-sensitive and can be up to 5 characters in length.
