Hi, the documentation around how numeric offsets are parsed from strings is a bit confusing, are they supposed to be treated as ISO8601 or POSIX ? e.g. select '2017-12-01 11:00:00 +11:00'::timestamp with time zone at time zone '+11:00'; timezone --------------------- 2017-11-30 13:00:00 select '2017-12-01 11:00:00 -11:00'::timestamp with time zone at time zone '+11:00'; timezone --------------------- 2017-12-01 11:00:00 The Table 8-12. Time Zone Input section at https://www.postgresql.org/docs/9.3/static/datatype-datetime.html seems to imply that numeric offsets would be treated as ISO8601. It's all a big confusing and would appreciate some clarification or pointer to documentation. Thanks
