// These two constructor calls should be equivalent
    rrulestr(
      "FREQ=WEEKLY;WKST=SU;COUNT=2;INTERVAL=1;BYDAY=MO,TU\n" +
      "EXDATE;TZID=America/Edmonton:20220502T090000"
    ,{dtstart: datetime(2022, 5, 2,  9, 0)}).all()

    rrulestr(
      "DTSTART;TZID=America/Edmonton:20220502T090000\n" +
      "FREQ=WEEKLY;WKST=SU;COUNT=2;INTERVAL=1;BYDAY=MO,TU\n" +
      "EXDATE;TZID=America/Edmonton:20220502T090000").all()

• [✅] Expected output

Should only return one element array with 20220503T090000 in it
