"The system time has changed" events after waking from sleep

Question

Sometimes when my computer running Windows 7 wakes up from sleep, it has to adjust the time. When this happens the following system event is logged:

<Event xmlns='http://schemas.microsoft.com/win/2004/08/events/event'>
    <System>
        <Provider Name='Microsoft-Windows-Kernel-General' Guid='{A68CA8B7-004F-D7B6-A698-07E2DE0F1F5D}'/>

When this happens (I noticed it twice until now) the old time always corresponds to the time when computer entered sleep. The problem is that if Windows Media Center is scheduled for recording during this time, it just skips it as if the computer was turned off. I never had this problem running Windows Vista on the same machine.

Any ideas what could be causing this problem and how to solve it are welcome.

Answer 1

Perhaps the system's clock battery is low on power ? See if changing it helps.
