　　Core-Switch-1#show clock
　　Core-Switch-1#show ntp status
　　Core-Switch-1#conf t
　　Core-Switch-1(config)# clock timezone GMT +8
　　Core-Switch-1(config)#service timestamps debug datetime msec localtime show-timezone
　　Core-Switch-1(config)#service timestamps log datetime msec localtime show-timezone
　　Core-Switch-1(config)#exit

　　默认情况下日志消息不包括日期和时间戳。
　　service timestamps {debug | log } uptime
　　service timestamps {debug | log } datetime [mesc] [localtime] [show-timezone] [year]
　　debug 参数 在调试输出时包括时间戳
　　log 参数 在每种日志消息中添加一个时间戳
　　uptime 在消息中包括路由器开机以来的时间
　　0w2d: #SYS-5-CONFIG_I : Configured from console by console
