Setting the switch date and time

The SAN48B-5 maintains the current date and time inside a battery-backed
real-time clock (RTC) circuit. The date and time settings are used for logging
events. Switch operation does not depend on the date and time; a switch with an
incorrect date and time value still functions properly. However, because the date
and time are used for logging, error detection, and troubleshooting, you should set
them correctly.
Complete the following steps to set the date and time of the switch.

Time zones

You can set the time zone for the switch by name. You can also set country, city or
time zone parameters.
If the time zone is not set with the new options, the switch retains the offset time
zone settings. The tsTimeZone command includes an option to revert to the prior
time zone format. For more information about the --old option, see the Fabric OS
Command Reference.
