Description This command sets the time zone and/or time zone offset for the device.
7450 ESS OS supports system-defined and user-defined time zones. The system-defined time zones are
listed in Table 21, System-defined Time Zones, on page 214.
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.
Default zone utc - The time zone is set for Coordinated Universal Time (UTC).
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.
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 dst-zone parameter is not required.
A user-defined time zone name is case-sensitive and can be up to 5 characters in length.
Values A user-defined value can be up to 4 characters or one of the following values:
GMT, BST, IST, WET, WEST, CET, CEST, EET, EEST, MSK, MSD, AST, ADT, EST,
