tasks calendar sync for all day tasks is broken

Since the last update (I'm now on 14.8.3) the calendar sync function doesn't work properly anymore:

All day tasks are now shown in the calendar one day before, e.g. a one day task being due on Tuesday is now shown on Monday in the calendar. This doesn't imply tasks with a fixed starting time.

My setting for calendar entries is: "Calendar entry starts with due date."

Also having this issue. Seems to line up with our change to daylight savings a few weeks ago.

Same issue here, might be related to this commit: https://github.com/tasks/tasks/commit/c3ce7a43fb061bca50ecbb353c0f05a4fb4acc43

Hoping for a fix in the next release. It's really annoying for my workflow. If there is something, that could speed this up, please tell.

I wonder whether downgrading could be a temporary solution for me but I'm scared of data loss or potentially enormous work for setting up the app again. Did anyone try this already?

Dear @abaker,

I really appreciate your long work on this app and promise to start donating again soon.... ;-) ...but please have a look on this bug which confuses me every day when looking at my calendars.

Obviously, these threads describe the same problem:

https://github.com/tasks/tasks/issues/4031 https://github.com/tasks/tasks/issues/3923

No change for v14.8.4 at my side.

Thanks!
