jQuery自定义中断多个元素

Question

如果有多个元素初始化，我有一个问题是更新计数器容器时间倒计时。在这种情况下，最后一个容器正在更新，并且倒计时秒被包含

插件代码

(function( $ ){

    var methods = {

        container: null,

        init : function(options) {
            var timestamp = $(this).data('release'), id = $(this).attr('id');
            if (!timestamp) return;

            methods.container = $('#' +id);
            console.log(methods.container)

            methods.times = {days: 0, hours: 0, minutes: 0, seconds: 0};
            time = new Date();

            methods.secondsToGo = timestamp - Math.round(time/1000) + (time.getTimezoneOffset() * 60);
            methods.calcTimes();
        },

        calcTimes: function() {
            secondsToGo = methods.secondsToGo;

            // Countdown end is in the past
            if (secondsToGo < 0) return;

            methods.container.show();

            // Calculate times
            methods.times.days  = Math.floor(secondsToGo/86400);
            if (this.times.days > 99) this.times.days = 99; // max. 2 digits
            secondsToGo = secondsToGo%86400;

            methods.times.hours = Math.floor(secondsToGo/3600);
            secondsToGo = secondsToGo%3600;

            methods.times.minutes  = Math.floor(secondsToGo/60);

            methods.times.seconds  = secondsToGo%60;

            methods.updateCounter();

            // Minus 1 second
            methods.secondsToGo--;

            // Loop
            setTimeout(function(){
                methods.calcTimes();
            }.bind(this), 1000);
        },

        updateCounter: function() {
            for(var prop in this.times) {
                pre = '';
                if (this.times[prop] < 10) pre = '0'; // min. 2 digits

                // number to string
                this.times[prop] = pre + this.times[prop];

                times = this.times; // ... because I can't use this.times in each-loop

                dnb = 0;

                methods.container.find('.number-block-' + prop).children('.number').each(function(){
                    $(this).html(times[prop][dnb]);
                    dnb++;
                })
            }
        }
    };

    $.fn.countdown = function(methodOrOptions) {
        if ( methods[methodOrOptions] ) {
            return methods[ methodOrOptions ].apply( this, Array.prototype.slice.call( arguments, 1 ));
        } else if ( typeof methodOrOptions === 'object' || ! methodOrOptions ) {
            // Default to "init"
            $obj = this

            return this.each(function() {
                //$(this).append(' - ' + $(this).data('x'));
                methods.init.apply( this, arguments );
            });
            //return methods.init.apply( this, arguments );
        } else {
            $.error( 'Method ' +  methodOrOptions + ' does not exist on jQuery.countdown' );
        }
    };


})( jQuery );

问题演示codepen

问题是插件循环内部的自我更新，以及容器上的更新如何影响最后一次加载。在每一秒更新所有容器会有什么明智的解决方法？
