Displays or sets the switch date and time.
SYNOPSIS
date ["newdate"]
DESCRIPTION
Use this command to display or set the date and time. All switches maintain current date and time in flash
memory. Date and time are used for logging events. Normal switch operation does not depend on the
date and time; a switch with incorrect date values continues to function properly.
This command sets a common date and time for the entire fabric. A change in date or time to one switch
is forwarded to the principal switch and distributed to the fabric. It may take up to 64 seconds for the
switches in the fabric to be synchronized. However, if an FCS policy is enabled, this command can be
executed only on the Primary FCS switch, and only the primary FCS switch can distribute the time stamp
to all other switches in the fabric.
If Virtual Fabrics are enabled, the date is set for the entire chassis, including all logical switches.
The date specified is always the local switch time, taking into account daylight saving time and the time
zone setup of the switch. Each switch takes care of converting the GMT time distributed fabric-wide to its
local time. Refer to tsTimeZone for more information on time zone support.
If the switch is operating in FICON Management Server mode (fmsMode), setting the date is subject to
the director clock alert mode (DCAM). If DCAM is 1, the operator issues a warning that the switch date is
about to change. The operator then prompts to confirm the change with a yes or no response.
NOTES
This command becomes read-only if external NTP synchronization is enabled. For more information,
refer to tsClockServer.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
