UTF?  I don't know the TLA.  But I'd say UTC 23:59:59.999..., perhaps
a second later than yours.

And I know we disagree on this, but, from:

    http://hpiers.obspm.fr/iers/bul/bulc/bulletinc.dat

 A positive leap second will be introduced at the end of June 2012.
 The sequence of dates of the UTC second markers will be:               
                
                          2012 June 30,     23h 59m 59s
                          2012 June 30,     23h 59m 60s
                          2012 July  1,      0h  0m  0s

(At least according to some authorities there is a 23:59:60.)

There's a proposal, recurrently deferred, now until 2015, to
eliminate leap seconds.  I'd prefer to see UTC abolished.  Let
the physicists use TAI; let the astronomers and IT people use
UT1, smoothed and announced a few weeks in advance.
