The problem is with using `pendulum.instance()` in the localized case. To see why, you can run this: ``` local_tz = pendulum.timezone('Europe/Zurich') start = local_tz.convert(datetime.datetime(2018, 10, 28, 2, 55), dst_rule=pendulum.PRE_TRANSITION) print(start.isoformat()) # '2018-10-28T02:55:00+02:00' print(pendulum.instance(start).isoformat()) # '2018-10-28T02:55:00+01:00' ``` Replacing your return statement with the following seems to resolve the issue: ```suggestion if not is_localized(value): return pendulum.instance(value, TIMEZONE) else: return utc.convert(value) ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
