          in_moscow = pendulum.parse("2018-01-01T09:00+0300")  # 9am in Moscow
          in_london = pendulum.UTC.convert(in_moscow)  # 6am in UTC
          dt_utc_from_moscow = pendulum_to_utc_datetime_without_tz(in_moscow)  # 6am, no timezone info
          dt_utc_from_london = pendulum_to_utc_datetime_without_tz(in_london)  # 6am, no timezone info
