Reference Guide

∙ 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 set to Greenwich Mean Time (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 reflect the time zone changes after the next reboot.
∙ Time zone settings persist across failover for high availability.
∙ Setting the time zone on any dual domain Backbone has the following characteristics:
– Updating the time zone on any switch updates the entire Backbone.
– The time zone of the entire Backbone is the time zone of switch 0.
Setting the time zone
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 must be set. However, you only need to set the time zone once on each switch because the value is written to nonvolatile
memory.
1. Connect to the switch and log in using an account assigned to the admin role and with the chassis-role permission.
2. Use the tsTimeZone command to review of set the time zone for the device.
∙ Enter tsTimeZone with no parameters to display the current time zone setting.
∙ Enter the --interactive option to list all of the time zones supported by the firmware.
∙ Enter timeZone_fmt to set the time zone by Country/City or by time zone ID, such as Pacific Standard Time (PST).
The following example displays and changes the time zone to US/Central.
switch:admin> tstimezone
Time Zone : US/Pacific
switch:admin> tstimezone US/Central
switch:admin> tstimezone
Time Zone : US/Central
Setting the time zone interactively
Use the following procedure to set the current time zone to PST using interactive mode:
1. Connect to the switch and log in using an account assigned to the admin role and with the chassis-role permission.
2. Enter the tsTimeZone --interactive command.
You are prompted to select a general location.
