yeah I seem to have MFC'd a BUG..
I confirmed they behaved the same. but I was looking at binary data
and didn't notice the date..

I'm preparing a revert, however it is a no-win situation as that leaves you open to 
sessions timing out immediately when the time is changed forward.

So, which is more important?
accurate timeouts or accurate reporting?

Ont thing that COULD be done would be to add the boot-time to the reported
times. this would never let a session time out too early, but would give 
slightly misleading report numbers if the time is adjusted. They would 
'adjust' to the same offset against the 'new time'.
i.e. if it shows 2 hours before "now" before the change it will show 2 
hours before the "new now" after the time is changed. This may be acceptable.
