How to use the sgp4.conveniences.sat_epoch_datetime function in sgp4

# The core SGP4 routines handled this fine, but my hamfisted
    # attempt to provide a Python datetime for "convenience" ran
    # into an overflow.
    a = '1 25544U 98067A   19366.82137887  .00016717  00000-0  10270-3 0  9129'
    b = '2 25544  51.6392  96.6358 0005156  88.7140 271.4601 15.49497216  6061'
    correct_epoch = dt.datetime(2020, 1, 1, 19, 42, 47, 134368)

    # Legacy API.
    sat = io.twoline2rv(a, b, wgs72)
    assertEqual(sat.epoch, correct_epoch)

    correct_epoch = correct_epoch.replace(tzinfo=conveniences.UTC)

    # Modern API.
    sat = Satrec.twoline2rv(a, b)
    assertEqual(conveniences.sat_epoch_datetime(sat), correct_epoch)

def test_sat_epoch_datetime():
    sat = Satrec.twoline2rv(LINE1, LINE2)
    datetime = conveniences.sat_epoch_datetime(sat)
    zone = conveniences.UTC
    assertEqual(datetime, dt.datetime(2000, 6, 27, 18, 50, 19, 733568, zone))
