What I'm getting with current sources is
regression=# select '0:00:59.99999999999999'::time as fourteen_dec;
fourteen_dec
--------------
00:00:59
(1 row)
which seems to be rounding in the wrong direction, and
regression=# select '0:00:59.999999999999999'::time as fifteen_dec;
ERROR: Bad time external representation '0:00:59.999999999999999'
That one seems reasonable, since this input is indistinguishable from
regression=# select '0:00:60'::time;
ERROR: Bad time external representation '0:00:60'
However, I also get
regression=# select now()::date+'0:00:59.999'::time;
?column?

2000-12-28 00:00:60.00-05

The cause is clear enough: the 59.999 seconds are being rounded off
to two digits for display. But it's unfortunate that this causes a
displayed output that will not be accepted as valid input. Perhaps
it would be a good idea to round off the seconds to display precision
*before* the value is broken down to hh/mm/ss.
