Invalid count if endTime is in past

[TheRulisp]

If I have a date that is in the past, I have this(53 days, 8 hours, 39 minutes...)

$("#time_countdown").countdown(
                        {
                            image: "/img/digits.png",
                            format: "dd:hh:mm:ss",                          
                            //endTime: new Date("<?=$date->format("D M j Y H:i:s")." GMT".$date->format("O");?>")
                            endTime: new Date("Mon Feb 1 2016 00:00:00 GMT+0800")
                        });
