Why does my Date object in Google Apps Script return NaN

Does Google Apps Script use a funky version of EcmaScript that can't parse a date? How can I parse the date 2011-04-11T19:25:40Z into a JavaScript Date Object in Google Apps Script?

My log output from below logs NaN.

function showDate(){
  var d = Date.parse("2011-04-11T19:25:40Z");
  Logger.log(d); // <-- Logs NaN
}
