The comment says 28 December 2016 but the expiry timestamp 3684182400
is actually 2016-09-30 00:00:00+0000, so they must be fairly confident
that current predictions of dUT1 remaining low until year end will be
borne out, and Bulletin C 52 will announce no change in July.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
