In Deluxe's "Specifications for Digital Cinema Source and DCP Content Delivery"
they say that subtitle <IssueDate> must be of the form yyyy-mm-ddThh:mm:ss

They don't explain it, and the standards don't say this (as far as I can see)
but as usual their QC fails <IssueDates> that don't meet this "spec" so here
we are.
