Sure. This has worked since PG 7.2 or so:
regression=# select '12:34:00 IRT'::timetz;
timetz
----------------
12:34:00+03:30
(1 row)
Also you can just do
regression=# select '12:34:00 +03:30'::timetz;
timetz
----------------
12:34:00+03:30
(1 row)
regression=#
The weird thing about this allegedly-POSIX notation is the combination
of a symbolic name and a further offset from it. Back when we didn't
have customizable timezone abbreviations, maybe there would be some
point in making that work, but I don't see the point now. I'm not
entirely convinced that it really is a POSIX-sanctioned notation,
either --- the POSIX syntax the zic code knows about is different.
