All switches in the fabric maintain the current clock server IP address in non-volatile memory. By
default, this value is LOCL, the local clock server of the Principal (when FCS not enabled) or Primary
(when FCS is enabled) switch. Changes to the clock server value on the Principal or Primary switch
are propagated to all switches in the fabric.
When a new switch enters the fabric, the time server daemon of the Principal or Primary switch
sends out the addresses of all existing clock servers and the time to the new switch. If a switch with
Fabric OS v5.3.0 or later has entered the fabric, it will be able to store the list of all the clock server
addresses; switches running Fabric OS versions earlier than v5.3.0 will ignore the new list
parameter in the payload and will update only the active server address.
If the active NTP server configured is IPv6, then distributing the IP address in the fabric will not be
possible to switches earlier than Fabric OS v5.3.0 because IPv6 is supported for Fabric OS v5.3.0
and later. The default value LOCL will be distributed to switches earlier than Fabric OS v5.3.0.
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 are stored as backup servers that can take over if the
active NTP server fails. The Principal or Primary switch synchronizes its time with the NTP server
every 64 seconds.

Setting the date

1. Log in to the switch using the default password (which is password).
2. Enter the date command, using the following syntax:

Setting time zones

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 one of the two following procedures to set the time zone. The first procedure requires you to
select the actual time zone and the second requires you to select the country location of the
switch.
The following procedure describes how to set the current time zone to Central Standard time using
timezonename mode.
