No, don't use UT1 for anything. This information won't be available
to most implementations. Either use TAI, which has no leap seconds,
or use UTC, which has the advantage of being easy to implement on Unix
and other operating systems. UT1 is only of specialist interest; the
most interesting thing about it is that it's used to define UTC.
TAI is even less accessable than UT1 on most systems. (If you know UTC, then
you know UT1 to within 0.9s, as I have pointed out before.) However, I can
see that pushing epoch offsets and UT1 isn't getting me any eager buyers,
selling points notwithstanding. In the interests of resolving this matter, I
will forego my aesthetic preferences and defer to RFC 3339. Leap second bugs
are inevitable, but unlikely to kill us (so far as mail-ng goes, at least).
