Correcting the time zone
If the switch time is off by hours (not minutes), set the time zone as follows:
1.
Log in as
admin
.
2.
Enter the
tstimezone -interactive
command and follow the prompts or enter the
tstimezone
command as follows:
tstimezone [
houroffset
[,
minuteoffset
]]
For Pacific Standard Time, enter
tstimezone -8,0
For Central Standard Time, enter
tstimezone -6,0
For Eastern Standard Time, enter
tstimezone -5,0
The default time zone for switches is UTC, which is 8 hours ahead of Pacific Standard Time. To
determine the
tstimezone
command parameter for other U.S. time zones, see
The parameters do not apply if the time zone for the switch has already been changed from the
default (UTC). Because the time value is stored in nonvolatile memory, you need only set this
once.
For more information about the command parameters, see the
tstimezone
command description
in the
Fabric OS Command Reference
.

Synchronizing local time using Network Time Protocol
You can synchronize the local time of the principal or primary FCS switch to a maximum of eight
external NTP servers. To keep the time in your SAN current, Hewlett Packard Enterprise
recommends that the principal or primary FCS switch has its time synchronized with at least one
external NTP server. The other switches in the fabric set their time automatically from the principal
or primary FCS switch.
All switches in the fabric maintain the current clock server value in nonvolatile memory. By default,
this value is the local clock server
<LOCL>
of the principal or primary FCS switch. Changes to
the clock server value on the principal or primary FCS switch are propagated to all switches in
the fabric.
