The TIME and TIMETZ types specify the hour, minute, second, microsecond of a day.

Instances can be created using the type names as a keyword, where the data must be formatted according to the ISO 8601 format (hh:mm:ss[.zzzzzz][+-TT[:tt]]).

SELECT TIME   '1992-09-20 11:30:00.123456';       -- 11:30:00.123456
SELECT TIMETZ '1992-09-20 11:30:00.123456';       -- 11:30:00.123456+00
SELECT TIMETZ '1992-09-20 11:30:00.123456-02:00'; -- 13:30:00.123456+00
SELECT TIMETZ '1992-09-20 11:30:00.123456+05:30'; -- 06:00:00.123456+00

The TIME type should only be used in rare cases, where the date part of the timestamp can be disregarded. Most applications should use the TIMESTAMP types to represent their timestamps.
