Event Start and Stop Time are in the wrong TZ

[Gradlon]

Problem and impact

When updating an event Time, the time is offset to the actually selected Tim. Ex: TZ is Europe/Zurich setting the time event start time to 08:30 results in a saved time of 10:30. Which is the UTC offset to the Time in Zurich. If the event is in winter time, the offset is only 1h.

If you update events several times without changing the time, the event is moved every time you save by 1 or 2 hours.

Pretix server runs inside Docker: Docker timezone is Europe/Zurich Image: pretix/standalone:2024.7

Expected behaviour

Expect the time in the input to be the same as the the time in the output.

Steps to reproduce

1. Create an event
2. add an event time
3. select a date and start date a time
4. look at the event date and time
