I have a date range field in a paragraph which is set to allow setting the timezone. Can someone suggest how I can alter the list of options used to select the TZ?
For the user profile form a simple form_alter exposes the timezone field options but when trying to alter the paragraph form I only see the timezone value already set as #date_timezone.
Possibly I can override the class used to build this list?
I could do this with JS without too much effort; but not the correct approach.
