How in the Flipclock.js plugin to set the countdown timer?
The documentation did not find this item, maybe someone has a ready-made solution?

$ (document) .ready (function () {
  var Clock = New Flipclock ($. Clock '), {});
});

I launched so much, I hope it will help)

jQuery (Document) .ready (Function ($) {
  var clock;
  var futurdate = new date ("May 29, 2016 0:00 PM EDT");
  var currentdate = new date ();
  var diff = futurdate.gettime () / 1000 - currentdate.gettime () / 1000;
  FUNCTION DAYDIFF (FIRST, SECOND) {
   Return (Second - First) / (1000 * 60 * 60 * 24);
  }
  If (DayDiff (CurrentDate, Futuredate) & LT; 100) {
   $ ('. Clock'). AddClass ('TwodayDigits');
  } else {
   $ ('. Clock'). AddClass ('threedaydigits');
  }
  if (Diff & LT; 0) {
   diff = 0;
  }
  Clock = $ ('. Clock'). Flipclock (Diff, {
   ClockFace: 'Dailycounter',
   Language: 'RU',
   Countdown: True.
  });
 });

Answer 2

Here is an example

// Instantiate A Coutdown Flipclock
Clock = $ ('. Clock'). Flipclock (Diff, {
  ClockFace: 'Dailycounter',
  ClockFaceOptions: {
    Countdown: True.
  }
});
Clock.Setcountdown (True);
Clock.face.ON ('Stop', Function () {
  // Add 24 Hours Worth Of Seconds to the Clock Face
  Clock.setFaceValue (24 * 60 * 60);
  clock.start ();
});
