In my experience, I've never come across such a case, so I can't really provide you with much information on it. Again, double check the log files with the displayed time (I would disconnect an interface, check the console output and then look for the appropriate log to compare it), and if you're sure there still is a problem, open a case with Cisco so they can help you determine the cause.
In addition, visit Cisco's site and perform a keyword search using your router model and IOS version to see what results you get back.
Best of luck!
