Missing hour during DST long day when shifting or calculating ranges #1162
Description
Issue Description
When iterating or shifting over times that cross the DST long day change, an hour is skipped when the time zone is set for something other than UTC.
The following demonstrates the issue where the first loop prints 2 hours for the span, but converting those same timestamps to UTC prints 3 hours (correctly). It's also strange that the tzinfo has to be set for the ISO timestamp containing the offset hours.
dts = arrow.get("2021-11-07T01:00:00-05:00", tzinfo="US/Central")
dte = arrow.get("2021-11-07T02:00:00-06:00", tzinfo="US/Central")
for dt in Arrow.range("hours", dts, dte):
print(dt)
print("---BREAK---")
dts = arrow.get("2021-11-07T01:00:00-05:00", tzinfo="US/Central").to("UTC")
dte = arrow.get("2021-11-07T02:00:00-06:00", tzinfo="US/Central").to("UTC")
for dt in Arrow.range("hours", dts, dte):
print(dt)
