Hey Alexey!

 AV> You've violated both RFC-3339 and my proposal.

I lied - one more for the road.  The attached one follows rfc-3339 to the
letter.  I am not convinced that your proposal is not in violation of rfc-3339
given the space between %T and %:z.

Life is good,
Maurice

... Wat se þe cunnað hu sliþen bið sorg to geferan.
    He who has experienced it knows how cruel a companion sorrow is.
