Cambios en "System timezone is not indicated to users"

This is coming from my question on the feature Multi-tenant Timezone: https://github.com/decidim/decidim/pull/5607

Apologies if this is better suited as a feature request, but Canada has six timezones, so it's problematic if the user doesn't know which TZ is being used.

At a minimum, we need the system's timezone to be indicated next to any time (e.g. \"10:00\" -> \"10:00 ET\"), so that the user knows how to adjust to local time.

Ideally, users would set their own timezone and have times adjusted to local, since it's a bit strange to imagine a meeting taking place entirely within British Columbia, and making them all use timing that is off by three hours.

Thanks for any suggestions, and apologies again if this is posted in the wrong section (we're learning!).
