Information Center Overview 455■ With the UTC time zone, the time stamp is in the format of "Mmm ddhh: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, rangingfrom 00 to 23, both "mm" and "ss" range from 00 to 59, "ms" ranges from000 to 999.■ "yyyy" is the year.■ "[GMT +|- hh:mm:ss]" is the UTC time zone, which represents the timedifference with the Greenwich standard time.Because switches in a network may distribute in different time zones, when thetime displayed in the time stamps of output information is the local time on eachswitch, it is not so convenient for you to locate and solve problems globally. In thiscase, you can configure the information center to add UTC time zone to the timestamp of the output information, so that you can know the standard time whenthe information center processing each piece of information. That is, you canknow the Greenwich standard time of each switch in the network based on theUTC record in the time stamp.To add UTC time zone to the time stamp in the information center outputinformation, you must:■ Set the local time zone■ Set the time stamp format in the output direction of the information center todate■ Configure to add UTC time zone to the output informationAfter the above configuration, the UTC time zone will be displayed in the outputinformation, 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 loginSysnameSysname 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 “BasicSystem Configuration and Debugging” on page 483.Note that there is a space between the sysname and module fields.ModuleThe module field represents the name of the module that generates systeminformation. You can enter the info-center source ? command in system view toview the module list. Refer to Table 340 for module name and description.
