Hello, I'm using PostgreSQL / SQLAlchemy 0.5.5 and I build my Table objects using the reflection feature :
{{{ metadata = schema.MetaData() metadata.reflect(bind=_engine) }}} I have a table which has a timestamptz column and when I try to insert a (for example) datetime(2009, 13, 12, 10, 12) in it, it fails with the following exception : <type 'exceptions.TypeError'>: can't compare offset-naive and offset-aware datetimes I guess it's because one side has a tzinfo and the other not. When I look at the documentation the constructor of sqlalchemy.types.DateTime has a "timezone" parameter which is False by default. However when I look at the column, timezone is set to True: Column(u'effective', PGDateTime(timezone=True), table=<content>) which is correct. Any idea how could I resolve this annoying problem ? Is it possible to set a default timezone in SQLAlchemy, or do I need to derive a concrete subclass of datetime.tzinfo, and pass it to every datetime() object ?
