Show timezone setting of event and allow to modify it
When creating an event, apparently the timezone is set to the timezone the user creating the event has set in their settings. But there is no indication in the event of the timezone and it is not possible to later change the timezone of an event.
I stumbled over this when using Torbrowser to setup my account (which has the timezone always set to UTC) and then created a couple of events and later realized that all the times were wrong when viewing the event with another browser. I changed the timezone in the user setting and updated the events, but the timezone was not updated. I had to manually calculate the offset and change the time.
I think the most intuitive approach would be to set the timezone based on the event location, not on the timezone the user creating the event has in their settings. And it would also be great if the timezone of an event could be modified.
I also think that it would be better to always show the times of events in the timezone of the event and not in the timezone of the user viewing the event (be it from their user settings or from their browser). When I'm in Tel Aviv and I want to attend a protest in Paris next week, I would want to know when the protest starts in Paris time and not in Tel Aviv time, even if that is what my browser is set to.
