Event Log in Vista, 2008, and Windows 7 question

I have a sample XML output of an event in from my System Event Log.  I'm curious to learn if anyone knows about these two tags:

<Data Name="SleepDuration">5246</Data>
<Data Name="WakeDuration">1683</Data>

Are these in miliseconds or seconds?  I can't any documentation on Microsoft's MSDN or technet discussing this stuff or deciphering the tags to see what they all mean.  Thank you in advance.

I believe it is the time in milliseconds taken to fall asleep and wake up respectively.

It couldn't possibly be the sleep time because that is 4.7 days (6836 minutes), which doesn't match those numbers remotely.
It also follows the the lead of things like "Driver Init Duration" and "Hiber Write/Read Duration" which are things that should only be on the order of thousands of milliseconds as well.
