30 Performing basic configuration tasks
You can set the time zone for a switch using the
tsTimeZone
command. The
tsTimeZone
command
allows you to:
• 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 such as PST
See the
tsTimeZone
command in the Fabric OS Command Reference Manual for more detailed
information about the command parameters.
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
tsTimeZone
setting supports daylight savings time. It 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.
• All switches are by default 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 started at the switch boot up reflect the time zone changes only after the next reboot.
• Time zone settings are persisted across failover for high availability.
Setting the time zone on a dual domain chassis has the following characteristics:
• Updating the time zone on any switch, updates the entire chassis.
• The time zone of the entire chassis is the time zone of the switch 0.
• For dual domain Directors (SAN Director 2/128), both switches in the same chassis will be in
the same time zone. Dual Domain chassis do not support different time zones on each domain.
The following procedure describes how to set the time zone for a switch. You must perform the procedure
on all switches for which the time zone needs to be set. However, you only need to set the time zone once
on each switch, because the value is written to nonvolatile memory.
How to set the time zone
1. Connect to the switch and log in.
2. Enter the
tsTimeZone
command as follows:
• Use
tsTimeZone
with no parameters to display the current time zone setting
• Use
--interactive
to list all of the timezones supported by the firmware.
• Use
timezone_fmt
to set the time zone by Country/City or by time zone ID, such as PST.
The following example shows how to display the current time zone setup and how to change the time zone
to US/Central.
The following procedure illustrates how to set the current time zone using interactive mode to Pacific
Standard Time (PST).
switch:admin> tstimezone [ --interactive ]/ [, timezone_fmt ]
switch:admin> tstimezone
Time Zone : US/Pacific
switch:admin> tstimezone US/Central
switch:admin> tstimezone
Time Zone : US/Central
