Quickly get timezone names and metadata from the IANA into your application in the format you want.

// From the IANA timezone theory file
// Names normally have the form AREA/LOCATION,
// where AREA is the name of a continent or ocean,
// and LOCATION is the name of a specific location within that region.
// North and South America share the same area, 'America'.
// Typical names are 'Africa/Cairo', 'America/New_York', and 'Pacific/Honolulu'.
