Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 99)

Refer to refer to Using Network Time Protocol on page 97 for a complete list of configurable regions and
cities.
Enter the clock timezone region/city command.
Example of setting and displaying the date and time in standalone mode:
switch# clock timezone America/Los_Angeles
Example of setting and displaying the date and time in VCS mode:
switch# clock timezone America/Los_Angeles rbridge-id all
NOTE
After upgrading your switch firmware, you might need to reconfigure the time zone information.
Displaying the current local clock and time zone
The show clock command returns the local time, date, and time zone.
NOTE
This command is currently supported on the local switch.
This example shows the local switch clock time:
switch# show clock
rbridge-id 1: 2012-05-04 16:01:51 America/Los Angeles
This example shows the clock time for all switches in the cluster (logical chassis cluster mode only):
switch# show clock rbridge-id all
2012-05-04 17:31:41 America/Los Angeles
This example shows the clock time for the switch with rbridge-id 16:
switch# show clock rbridge-id 16
rbridge-id 16: 2012-05-04 18:18:51 America/Los Angeles
Removing the time zone setting
Use the no clock timezone command to remove the time zone setting for the local clock. This
operation returns the local time zone to the default value (GMT). When using the no operand, you do
not need to reference a timezone setting.
Enter the no clock timezone command.
This example removes the time zone setting in standalone mode:
switch# no clock timezone
This example removes the time zone setting in VCS mode:
switch# no clock timezone rbridge-id 5
Synchronizing the local time with an external source
Use the ntp server command to synchronize the local switch time with an NTP server. You can
configure up to five IP address. At least one IP address in the list must be a reachable, configured NTP
server or the request will fail.
The following example synchronizes the time on the local switch with the ntp server at 192.168.10.1.
