Hi Andy,
If a router is configured to get the time from a Network Time Protocol (NTP) server, the times in the router's log entries may be different from the time on the system clock if the [localtime] option is not in the service timestamps log command. In the example below, the router gets its time from an NTP server and theservice timestamps log datetime command is issued. The show clockcommand displays a time of 14:12:26, yet when a configuration change is made immediately after the show clock command, the log message shows a time of 21:12:28, as shown in this example:
clock timezone PST -8
clock summer-time PDT recurring
service timestamps debug datetime
service timestamps log datetime
logging buffered 16000 debugging
ntp clock-period 17179272
ntp server 161.181.92.152
router#show clock
14:12:26.312 PDT Thu Apr 27 2000
router#config t
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#exit
router#
Apr 27 21:12:28: %SYS-5-CONFIG_I: Configured from console by vty0
Resolution
Add the [localtime] option to the service timestamps log command. For example, if the current configuration is service timestamps log datetime, issue this global configuration command:
router(config)#service timestamps log datetime localtime
router(config)#^Z (ctrl z to exit)
router#write mem
The times should now be synchronized between the system clock and the log message timestamps.
