Describe the bug

When I visit a meeting that stretches for multiple days, I encounter many issues that are really confusing. Let's take a look at this event on nightly, which has the start date 03.05.2025, 13:00 and end date 19.11.2026, 18:00.

The event is displayed like this:

The following things are suboptimal or simply wrong:

• Only the year of the start date is displayed, giving the impression the event ends in 2025
• The time is displayed as a span, suggesting the event takes place only on one day
• There is an AM/PM indication on a 24h clock, which does not make sense
• There is a time zone indication which really only makes sense on platforms used in a transnational/international context.

To Reproduce

1. Visit: https://nightly.decidim.org/assemblies/neighborhoods/f/55/meetings/13?locale=en
2. See all errors

Expected behavior

The current layout works well for single day events, except for the AM/PM and time zone parts.

I would improve the following things:

• Remove AM/PM indications on 24h clocks
• display time zones only when the indicated time is different from the one used by the user
• If the meeting stretches for multiple days, display the date before the time in the span (3. May 2025, 13:00 – 19. November 2026, 18:00)
• display two individual calendar fields for the dates, each containing the corresponding year
