Autofill on "Days of the week" events is 1h off

[ADecametre]

The problem

Recently I was trying to plan a weekly meeting. After autofilling my availabilities, it took me a few hours to realize that they were all 1h off. I then had to manually adjust all my availabilities since there's no option to change the autofill timezone.

How to reproduce

1. Live in a country that uses daylight saving time.
2. Create a Timeful event with Days of the week.
3. Click on Add availability to autofill.
4. Select a week that's after a time change.
5. Realize that all events are one hour off.

I could not reproduce this issue on an Timeful event with Specific dates.

Is this still an ongoing issue? What would be reliable conditions for the bug to occur?
