Date and time settings
2
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,
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 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.
Use the following procedure to set the device time zone:
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 command.
• Use tsTimeZone with no parameters to display the current time zone setting.
• Use --interactive to list all of the time zones supported by the firmware.
• Use timeZone_fmt to set the time zone by Country/City or by time zone ID, such as Pacific
Standard Time (PST).
Example of displaying and changing 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
