# What this PR does
This older version of recurring_ical_events does not call the pytz
.normalize() function, which can cause some invalid datetime objects to
return when a DST swap happens. For example: Nov 3, 2024 9:00 AM CDT
instead of the correct 8:00 AM CST). By calling tz.normalize on the end
date and checking if the time zone information changed, we can detect
when DST starts/stops and adjust the end date accordingly.
