>>> I have this form mysql:

I think you want something like:
PG=# select '23:59' as timestring, '23:59'::time as format ;
timestring | format
------------+----------
23:59 | 23:59:00
(1 row)
Or as you seem to have "." as separator (tough it depends probably on
the locale if 23.59 is a time or not)
PG=# select '23.59' as timestring, replace('23.59', '.',':')::time as
format;
timestring | format
------------+----------
23.59 | 23:59:00
Adapted to your example:
SELECT tid_in, replace(tid_in, '.', ':')::time as format FROM timmar;
All in all, "as" should work as you think, it's more the time conversion
/ from-string-parsing that's different.
