Add option to include time zones

Is your feature request related to a problem? Please describe.
I noticed the times can be confusing for people joining from multiple different time zones in the U.S. and looked for some way to add a CDT (Central Daylight Time) next to the listed time for the Brigade Congress 2021 events.

Here's a link to the instance of Decidim, this page is one of the day's events for the Code for America Brigade Congress, October 15-17, 2021:
https://cfa.osp.cat/conferences/congress/program/52

The times required this format: dd/mm/yyyy hh:ii

Describe the solution you'd like
I haven't found a way to add the time-zone next to the event times, and I imagine this would be a feature that other people using the software may need.

Describe alternatives you've considered
Another possibility could be a separate entry field specific to time zones.

Additional context
I hope the link to the Decidim instance above will help to clarify the problem. I also uploaded a screenshot of the schedule page.

Does this issue could impact on users private data?
No impact on private data.

I imagine this feature is inexpensive, or possible to list on a repo for someone looking to contribute?
