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…

@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".
