Some recurring events not showing up

[secastles]

Hi,
In the last two weeks I've experienced two problems:

1. Some calendar events started to show up a day earlier than scheduled.
2. All new (added as of this week) recurring events do not show up at all.

In a bit of haste I replaced the events that were showing up a day early with new events. I thought that by deleting and re-adding them it might fix the issue. But then I discovered that all newly added recurring events don't show up at all. I still have an old recurring event that shows up fine though. I'm pasting relevant iCal exports below.

This is a recurring event that still shows correctly:

BEGIN:VEVENT
DTSTART;TZID=America/New_York:20190928T090000
DTEND;TZID=America/New_York:20190928T093000

END:VEVENT

This is a recurring event that does not show correctly. This event, like the event above, has an end date:

BEGIN:VEVENT
DTSTART;TZID=America/New_York:20191107T013000
DTEND;TZID=America/New_York:20191107T020000

This is a newly added recurring event without an end date. This does not show correctly:

BEGIN:VEVENT
DTSTART;TZID=America/New_York:20191107T023000
DTEND;TZID=America/New_York:20191107T030000

TRANSP:OPAQUE
END:VEVENT

This is a newly added event that works correctly but is not recurring:

BEGIN:VEVENT
DTSTART:20191107T083000Z
DTEND:20191107T090000Z
DTSTAMP:20191106T160251Z

LOCATION:
SEQUENCE:1
STATUS:CONFIRMED
SUMMARY:Test7 - this does not repeat
TRANSP:OPAQUE
END:VEVENT

As far as I can tell the difference between the recurring event that shows correctly and the ones that do not is that:

• The event that shows correctly has an end date
• The events that do not show correctly either:
  • Do not have an end date
  • Include a time in their end date

I'm not sure why there is a discrepancy from Google. My old event doesn't have a time in the UNTIL field but my new event does.

Any ideas for further troubleshooting?

Problem resolved itself over the weekend. Recurring events are now showing up correctly. I still think there's a bug though. The problem was reproducible for about a two week period where countries were shifting off of DST. Might also be related to #MagicMirrorOrg/MagicMirror#1798
