Yep. The "expiry" field is equal to the UNIX timestamp at which the
session will expire. To get a list of sessions that have already expired,
you can use this:
$query = "SELECT * FROM sessions WHERE expiry < " . time();

That sounds about right. You might want to try:
if (!session_is_registered("NameOfUser")) {
//restart session
}
Although I don't know if that function is reliable with the custom session
handler...I think it should be though.
I've been using that exact same session handler for several weeks in one of
my scripts and it works great....
