Allow times of 24:00:00 to match rounding behavior:

Browse Source 
regression=# select '23:59:59.9'::time(0);
	   time
	----------
	 24:00:00
	(1 row)

	This is bad because:

	regression=# select '24:00:00'::time(0);
	ERROR:  date/time field value out of range: "24:00:00"

The last example now works.
