Setting the date and time
The date and time are maintained by the switch's battery-backed RTC circuit. Incorrect date and time will
not affect switch operation. However, setting the date and time accurately is important because these
values are used for logging, error detection, and troubleshooting.
Setting the date
Procedure
1.
Log in to the switch using the admin account. The default password is
password
.
2.
Enter the
date
command:
date "mmddHHMMyy"
The values are as follows:
mm
is the month; valid values are 01 through 12.
dd
is the date; valid values are 01 through 31.
HH
is the hour; valid values are 00 through 23.
MM
is minutes; valid values are 00 through 59.
yy
is the year; valid values are 00 through 99. (Values greater than 69 are interpreted as 1970 through
1999; values less than 70 are interpreted as 2000-2069.)

Setting the time zone
Users with administrative permissions can set the time zone for the switch by the zone name (such as
PST), by the country and city, or by time zone location (such as US/Central).
If you do not set the time zone, the switch retains the previous zone settings. The
tstimezone
command includes an
--old
option, which reverts to the prior time zone format. For more information,
see the Fabric OS Command Reference.
The
tstimezone
command has three options:
Procedure
1.
The
tstimezone
command with no parameters displays the current time zone setting.
2.
The
tstimezone --interactive
command displays all time zones supported in the firmware.
3.
The
timeZone_fmt
command sets the time zone based on the country and city, or a time zone ID,
such as PST, that you enter.
This command requires administrator privileges.
The time zone setting has the following characteristics:
• Automatically adjusts for Daylight Savings Time.
• Changing the time zone updates the local time zone setup and is reflected in local time calculations.
• By default, switches are in the GMT time zone (0,0). If all switches in a fabric are in one time zone, you
can keep the time zone setup at the default setting.
