You can't add two times: What is 2 o'clock plus 3 o'clock?

You have to add a duration of time to a time, i.e. an INTERVAL. A TIME and an INTERVAL HOUR TO SECOND look exactly the same, but are different.

This will work:

     TIME '12:12:12' + interval '03:03:03' hour to second

To change a TIME to an Interval you simply substract midnight:

     TIME '12:12:12' - TIME '00:00:00' HOUR TO SECOND

     select TIME '12:12:12' + (TIME '12:12:12' - TIME '00:00:00' HOUR TO SECOND);
