SSO sesssion start time?

[Cantor, Scott]

There is no such thing. The closest is the time at which individual AuthenticationResults are created, the AuthenticationInstant in the assertions being I think one of those, I think the latest one IIRC. There is no single value unless only a single authentication method is active.

The active results that exist are pulled out into the AuthenticationContext under the ProfileRequestContext, you'd have to review the Javadocs for all of the relevant details.
