// Where could such data be found
// In js_i18n_data in http://go/i18n_dir, we have a bunch of files with names
// like TimeZoneConstant__<locale>.js
// We strongly discourage you to use them directly as those data can make
// your client code bloated. You should try to provide this data from server
// in a selective manner. In typical scenario, user's time zone is retrieved
// and only data for that time zone should be provided.
// This piece of data is in JSON format. It requires double quote.
