Correct problem where daylight savings time was not automatically determined when creating new time structures from date/time parts, which resulted in incorrect "number of seconds since epoch" results.
Also added optional is_local_time argument to SecondsToParts function, CreateDateFromSeconds transform, CreateTimeFromSeconds transform, and CreateDateTimeFromSeconds transform. The new argument fixes incorrect inverse translations from SecondsFromParts(is_local_time := TRUE) results.
