How can I only keep the most relevant TZINFO object in ruby when I have two with the same timezone.
E.g. Australia returns "Asia/Tokyo" as one of its timezones, but Japan also has "Asia/Tokyo" as a timezone. How could I only keep the identifier for Japan?
I'm currently using TZInfo::Country.all.map do |country| to get a list of countries, and then calling #zone_identifiers
