Realized my previous explanation could be better. The primary difference is that when you use WITH TIME ZONE Postgres stores the date/time as UTC and knows it has done so. If you use WITHOUT TIME ZONE it does not. For purposes of comparison it then makes the assumption the WITHOUT date/time data is whatever is set for local time. In the situation you describe above you would need to either set local time at UTC or use AT TIME ZONE to make the correction.
