Since clean installing Windows 8, my computer has decided that it will not stay in hibernation until called upon to wake up.
This is what Event Viewer has to say about it.

The system time has changed to 2013-04-07T08:22:08.500000000Z from 2013-04-07T03:42:17.309703500Z.
Change Reason: System time synchronized with the hardware clock.
I have no idea what is causing this. It has happened since I first clean installed Windows and before anything else was installed. I get the impression that it is a Windows 8 issue as I have seen others complain about similar problems in the Windows 8 forum.
There is nothing scheduled other than defragmenter, and that is a weekly schedule, not 04:00 hrs daily. OK, so five hours in hibernation is better than nothing, but I would still like to know what wakes it up.
Why do I like the hibernate function? Mainly because I haven’t always finished what I am doing by close of day, it saves on power and it stops the computer sucking in dust throughout the night.
If anybody out there has an an identical problem and solved it, please leave a suggestion in comments. It is very rare that I need outside help to sort problems, but this one has me beat..
