■

With the UTC time zone, the time stamp is in the format of "Mmm dd 
hh:mm:ss:ms yyyy [GMT +|- hh:mm:ss]". 

Each field is described as follows:

■

"Mmm" represents the month, and the available values are: Jan, Feb, Mar, Apr, 
May, Jun, Jul, Aug, Sep, Oct, Nov, and Dec.

■

"dd" is the date, which shall follow a space if less than 10, for example, " 7".

■

"hh:mm:ss:ms" is the local time, where "hh" is in the 24-hour format, ranging 
from 00 to 23, both "mm" and "ss" range from 00 to 59, "ms" ranges from 
000 to 999.

■

"yyyy" is the year.

■

"[GMT +|- hh:mm:ss]" is the UTC time zone, which represents the time 
difference with the Greenwich standard time. 

Because switches in a network may distribute in different time zones, when the 
time displayed in the time stamps of output information is the local time on each 
switch, it is not so convenient for you to locate and solve problems globally. In this 
case, you can configure the information center to add UTC time zone to the time 
stamp of the output information, so that you can know the standard time when 
the information center processing each piece of information. That is, you can 
know the Greenwich standard time of each switch in the network based on the 
UTC record in the time stamp. 

To add UTC time zone to the time stamp in the information center output 
information, you must:

■

Set the local time zone

■

Set the time stamp format in the output direction of the information center to 
date

■

Configure to add UTC time zone to the output information

After the above configuration, the UTC time zone will be displayed in the output 
information, like the following:

%Dec  8 10:12:21:708 2006 [GMT+08:00:00] 4210 SHELL/5/LOGIN:- 1 - 

VTY(1.1.0.2) in unit1 login

Sysname is the system name of the local switch and defaults to "4210".

You can use the sysname command to modify the system name. Refer to “Basic 
System Configuration and Debugging” on page 483.

Note that there is a space between the sysname and module fields.

The module field represents the name of the module that generates system 
information. You can enter the info-center source ? command in system view to 
view the module list. Refer to Table 340 for module name and description.
