ValueError: RRULE UNTIL values must be specified in UTC when DTSTART is timezone-aware #71

It might be the problem of google calendar or other ics handling applications.

I found an event that is repeatedly scheduled. And I got an error when I load the calendar like icalevents.icalevents.events(url=https://xx/x/xx.ics, start=start, end=end) where start and end are datetime.datetime object: ValueError: RRULE UNTIL values must be specified in UTC when DTSTART is timezone-aware

If I read the *.ics file, there is an event which is something like this:

DTSTART;TZID=Asia/Tokyo:20200610T103000
DTEND;TZID=Asia/Tokyo:20200610T110000
RRULE:FREQ=WEEKLY;WKST=SU;UNTIL=20201130;BYDAY=WE

END:VEVENT

As mentioned by the error message, UNTIL is 20201130 which is only date information not datetime with timezone. But can we assume date object as date + datetime.datetime.time(0, 0) in the same timezone? OR prepare a method to fix the *ics?

Seems to be broken on the latest 0.1.25 release. I can reproduce it on that but I have it working on 0.1.24
