Hi, I would like to implement item from TODO list: "Improve TIMESTAMP WITH TIME ZONE subtraction to be DST-aware".
To compute interval properly, we need time zone. Currently in timestamp we don't have time zone information, so I would use actual session time zone for computations. This can cause problems in the future, when TZ info will be saved in DB (this is also on TODO list). In such case, user may suspect, that stored TZ will be used, and probably behavior of subtraction will change. Anyway, I think, that using session TZ now is better than not using it at all. Can I start with implementation?
