rrule generator skipping window during exit of DST

[MarvinWinks]

When using rrule to generate recurring events using a dttime having timezone=America/New_York, the returned times skip an hour, the second "go-around" for 1 AM ET.

Sample code:

from datetime import datetime
from dateutil import tz
from dateutil.rrule import rrule, SECONDLY

tz_ny = tz.tz.gettz('America/New_York')
dtstart = datetime(2024, 11, 3, 1, 52, 3, tzinfo=tz_ny)
for d in list(rrule(count=10, freq=SECONDLY, interval=240, dtstart=dtstart)):
    print(d)

Actual output

2024-11-03 01:52:03-04:00
2024-11-03 01:56:03-04:00
2024-11-03 02:00:03-05:00 # 02 unexpected
