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 change 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
The following procedure describes how to set the current time zone using
interactive mode to Pacific Standard Time.
1. Enter the tsTimeZone command as follows:
switch:admin> tstimezone --interactive
You are prompted to select a general location.
Please identify a location so that time zone rules can be set correctly.
2. Enter the appropriate number or Ctrl+D to quit.
3. At the prompt, select a country location.
4. At the prompt, enter the appropriate number to specify the time zone region
or Ctrl+D to quit.
Synchronizing local time
To synchronize the local time of the principal or primary switch with that of an external NTP server,
follow these steps.
1. If necessary, log on to the switch by Telnet, using the admin account.
2. Enter the tsClockServer command:
switch:admin> tsclockserver
"<ntp1;ntp2>"
In this syntax, ntp1 is the IP address or DNS name of the first NTP server, which the switch must be
able to access. The variable ntp2 is the second NTP server and is optional. The operand
"<ntp1;ntp2>" is optional; by default, this value is LOCL, which uses the local clock of the principal
or primary switch as the clock server.
The tsClockServer command accepts multiple server addresses in IPv4, IPv6, or DNS name
formats. When multiple NTP server addresses are passed, tsClockServer sets the first obtainable
address as the active NTP server. The rest will be stored as backup servers that can take over if the
active NTP server fails. The principal or primary FCS switch synchronizes its time with the NTP
server every 64 seconds.
switch:admin> tsclockserver
LOCL
switch:admin> tsclockserver "132.163.135.131"
switch:admin> tsclockserver
132.163.135.131
switch:admin>
The following example shows how to set up more than one NTP server using a DNS name:
switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net"
Updating Clock Server configuration...done.
Updated with the NTP servers
Changes to the clock server value on the principal or primary FCS switch are
propagated to all switches in the fabric
