I don't have the time to keep up with all the details. But this
example does raise related issues for me about how you'd map it to a
standard date-time object. So I see Saašha's point.
I'm also a bit confused why we have both "u" and "x" (aside from
legacy); what the difference really is between "masked" and
"unspecified."
