Wiki / Functions

Add an interval to a timestamp with time zone, computing times of day and daylight-savings adjustments according to the time zone named by the third argument, or the current TimeZone setting if that is omitted. The form with two arguments is equivalent to the timestamp with time zone + interval operator.

English manual coverage begins with PostgreSQL 7.1. Source history and runtime observations have their own recorded version boundaries.
