Zendesk timezones are represented by friendly names that map to tz database names. For example, an API request returns "Eastern Time (US & Canada)" instead of "America/New_York". You can map the friendly names to the tz database names by referencing the Constants > Mapping section of the Ruby on Rails TimeZone object doc. https://developer.zende…

@lightyrs I don’t remember how I was using this at all, maybe you’ll find if more useful array flipping the keys and values, the reason there are dupes are because of several values mapping to the same key

@stevelacey Thanks for your work. I ended up using this like:

def zone_name(zone_string)
  ActiveSupport::TimeZone::MAPPING.select {|k, v| v == zone_string }.keys.first || IANA_TO_ACTIVERECORD_TIMEZONE_MAPPING[zone_string]
end

I believe the IANA timezone should be "America/Kentucky/Louisville" rather than "America/Louisville".
