Setting the Date and Time
The date and time settings are used for event logging, error detection, and troubleshooting. However, device operation
does not depend on the date and time; a device with incorrect date or time values still functions properly.
You can synchronize the local time of the principal or primary fabric configuration server (FCS) device to that of an
external Network Time Protocol (NTP) server.
Perform the following steps to set the date and time:
1. Log on to the device as admin.
2. Enter the date ["new-date"] command at the command line.
The "new-date" variable specifies the new date and time and is enclosed in double quotation marks. This variable
is optional; if omitted, the current date and time are displayed. The date and time are specified as a string in
mmddhhmmyy format:
•
mm: Specifies the month. Valid values are 01 through 12.
•
dd: Specifies the date. Valid values are 01 through 31.
•
hh: Specifies the hour. Valid values are 00 through 23.
•
mm: Specifies the minutes. Valid values are 00 through 59.
•
yy: Specifies the year. Valid values are 00 through 37 and 70 through 99. Year values from 70 to 99 are interpreted
as 1970 to 1999; year values from 00 to 37 are interpreted as 2000 to 2037.

Setting the Time Zone
The default time zone is Coordinated Universal Time (UTC). The time zone must be set only once because the value is
stored in nonvolatile memory.
Perform the following steps to set the time zone:
1. Log on as admin.
2. Use the tsTimeZone --interactive command and follow the prompts, or enter the tsTimeZone
[houroffset[,minuteoffset]] command as follows:
For Pacific Standard Time, enter tsTimeZone -8,0 .
For Central Standard Time, enter tsTimeZone -6,0 .
For Eastern Standard Time, enter tsTimeZone -5,0 .
