Hi,
I have a 3750X stack I just put together. Some of the switches have been shelved for a couple of years so I think the battery might be going/gone on it. In the meantime I would just like to be able to have the logs timestamped with the correct time/ date. Is this possible?
See below
MTL-CORE3750XFL12-1#show log
.....
*Mar 1 00:06:50 UTC: %SYS-5-CONFIG_I: Configured from console by vty0 (172.16.1.131)
MTL-CORE3750XFL12-1# show clock
14:16:50.375 UTC Thu Aug 28 2014
Solved! Go to Solution.

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 clock command 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 of21:12:28, 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
Add the [localtime] option to the service timestamps log command. For example, if the current configuration isservice 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.
