Yes it should (i.e. unless it cause a regression elsewhere) be in 1.1.9 but
it problably won't be in any 1.1.8.x micro releases.
Could you provide more details about the problem you encountered ? That
would help ensure the feature doesn't get broken later.
Did you try any Mono release before 1.1.8 ? If so was it working ? (i.e. is
it a regression ?)
The only fixed case I can think of is if you're using Active Directory
(which requires optional mutual authentication to works).

Yes it is. ASN.1 encoded dates are stored in UTC format. Thanks for spotting
I'll be fixing this ASAP (i.e. it should also be in 1.1.9).
