tsTimeZone
Displays or sets the system time zone.
Synopsis tstimezone --interactive
tstimezone timezonename
tstimezone --old hourOffset [, minuteOffset]
Description Use this command to display or set the system time zone.
All switches maintain the current time zone setup in nonvolatile memory. Changing the time zone
on a switch updates the local time zone setup and is reflected in local time calculations.
All switches are by default in the 0,0 time zone:, which is, GMT. If all switches in a fabric are located
in the same time zone, you may leave the default time zone setup.
Time zone is used in computing local time for error reporting and logging. An incorrect time zone
setup does not affect the switch operation in any way.
System services started during the switch boot reflect a time zone change only at the next reboot.
The time zone can be specified in two ways, by name or in an hours and minutes offset format:
1. The offset format is specified with the --old option, followed by an hour offset value and
optionally a minute offset value.
2. The time zone name format uses the timezone database, which automatically adjusts for
Daylight Saving Time.
By default, the switch is in offset mode (--old), with zero offsets, that is, time is displayed in GMT.
Use tsTimeZone timezonename to change the offset format to the timezone name format.
When executed without parameters, this command displays the current time zone configuration in
the format in which it was set.
• Negative hour offset values mean that the local time is behind GMT; for example, -8,0 is
GMT-08:00.
• Positive hour offset values mean the that local time is ahead of GMT; for example, 3,0 is
GMT+03:00.
Note The execution of this command is subject to Admin Domain restrictions that may be in place. Refer
to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability"
for details.
Operands This command has the following operands:
--old Specifies the time zone in the offset format.
hourOffset Specifies the number of hours relative to GMT. This operand must be
specified as an integer. Valid values are -12 through 12. This operand is
required with the --old option.
minuteOffset Specifies the number of minutes relative to hour offset. This operand must be
specified as an integer and is valid only with the --old option. Valid values
are -30, 0, or 30. This operand is optional; if not specified, the value defaults
to 0.
