  // The `timezoneJS.Date` object gives you full-blown timezone support, independent from the timezone set on the end-user's machine running the browser. It uses the Olson zoneinfo files for its timezone data.
  //
  // The constructor function and setter methods use proxy JavaScript Date objects behind the scenes, so you can use strings like '10/22/2006' with the constructor. You also get the same sensible wraparound behavior with numeric parameters (like setting a value of 14 for the month wraps around to the next March).
  //
  // The other significant difference from the built-in JavaScript Date is that `timezoneJS.Date` also has named properties that store the values of year, month, date, etc., so it can be directly serialized to JSON and used for data transfer.
