All Day events not working properly

[cpw7922]

My all day events are showing up as 8pm-8pm instead of All Day events. Non-All Day events show up just fine. Not sure if all_day or is_all_day is being looked at

I have the same issue. My all day events are shifted -4 hours off of midnight (which corresponds to my time zone). HA and my docker container have the correct timezone set and all appointments that are not all day appear with the correct start/end times in the calendar. I am happy to try and debug/track this bug down, but I'm new to HA plugins, so any pointers on where to look would be appreciated.

Same here. "is_all_day: true in the payload but the attribute "all_day" is set to false. On top the entry shows up on two days as the day is shifted by one hour: message: Birthday all_day: false start_time: '2020-12-14 01:00:00' end_time: '2020-12-15 01:00:00' location: displayName: '' locationType: default uniqueIdType: unknown address: {} coordinates: {} description: '' offset_reached: false data:
