I kind of suspect not, since this fails:

david=# select '12:24:53 654'::time;
ERROR:  invalid input syntax for type time: "12:24:53 654"
LINE 1: select '12:24:53 654'::time;              ^

I would have guessed that the time parser gets to a state where it knows it is dealing with a ISO-8601-style time. But
Ihave not looked at the code, of course.
