Meaning of "sleep time" in Vista Event Viewer?

[EhrFred]

While troubleshooting an unexpected restart (turned out to be Windows
Update), I stumbled across Event Viewer (System) entries like:

The system has resumed from sleep.

Sleep Time: 3/3/2008 2:08:50 PM
Wake Time: 3/3/2008 5:43:38 PM

Wake Source: Unknown

I have searched Google and support.microsoft.com to no avail, trying
to understand what these two times mean. I would appreciate any
pointer or any direct explanation.

Thanks!

That's self explanatory.

The computer entered the Sleep State and then resumed from the Sleep State.
Go to start, click Help and Support. In the Search Box, type Sleep State.

Well, no offense but if it was self-explanatory then I hope I would
not have asked. <g>

Perhaps my confusion is the result of MSFT's carelessness in applying
or not applying the local culture to the variety of timestamps
reported in Event Viewer. So with my timezone = EST, now that I stare
at Event Viewer once more,

the "Logged" time = 3/3/2008 12:43:40 PM
and if I add 5 hours to convert to UTC then I get: Wake Time: 3/3/2008
5:43:38 PM

I had noticed some search hits about misleading / lazy application of
local timezone but it didn't register until I saw your response.

Thank you.
