leveraging login context expiration on login form

[Christopher Bongaarts]

Before I go RTFS I thought I'd see if anyone already has the answer handy...

Is there a way, from within login.jsp, to get the time (preferably in 
UNIX time_t but any format will do) that the current loginContext will 
expire?  A cursory examination of the methods of loginContext didn't 
reveal anything obvious.

The goal is to pass this time as a parameter to a page on another site, 
so the other site can make an educated guess whether returning the user 
to the IdP will allow them to continue their login process, or if it is 
likely to blow up.
