Time zone settings

You can set the time zone for a switch by name. You can specify the setting using country and city
or time zone parameters. Switch operation does not depend on a date and time setting. However,
having an accurate time setting is needed for accurate logging and audit tracking.
If the time zone is not set with new options, the switch retains the offset time zone settings. The
tsTimeZone command includes an option to revert to the prior time zone format. For more
information about the tsTimeZone command, refer to the Fabric OS Command Reference.
When you set the time zone for a switch, you can perform the following tasks:
•Display all of the time zones supported in the firmware.
•Set the time zone based on a country and city combination or based on a time zone ID,l
such as PST.
The time zone setting has the following characteristics:
•Users can view the time zone settings. However, only those with administrative
permissions can set the time zones.
•The setting automatically adjusts for Daylight Savings Time.
•Changing the time zone on a switch updates the local time zone setup and is reflected in
local time calculations.
•By default, all switches are in the GMT time zone (0,0). If all switches in a fabric are in one
time zone, it is possible for you to keep the time zone setup at the default setting.
•System services that have already started will reflect the time zone changes only after the
next reboot.
•Time zone settings persist across failover for high availability.
Setting the time zone on a dual domain director has the following characteristics:
•Updating the time zone on any switch updates the entire director.
•The time zone of the entire director is the time zone of switch 0.
