My vote is for SOURCE_DATE_UTC, and i agree with Brendan that we should
take the opportunity to define this as strictly and narrowly as possible
(i.e. end in a 'Z', none of the other offsets), so that people relying
on it know they're getting a fixed thing, and don't have to implement
any fancy parsing/offsetting code if they're not already using an
ISO8601-compliant date-parsing library.

I don't like this one, because apparently it's too hard to spell :)
