formatDate : function(time) {
if(time!=null){
var datetime = new Date();
datetime.setTime(time);
var year = datetime.getFullYear();
var month = (datetime.getMonth() + 1)<10?"0"+(datetime.getMonth() + 1):(datetime.getMonth() + 1);
var date = datetime.getDate()<10?"0"+datetime.getDate():datetime.getDate();
var hour = datetime.getHours()<10?"0"+datetime.getHours():datetime.getHours();
var minute = datetime.getMinutes()<10?"0"+datetime.getMinutes():datetime.getMinutes();
var second = datetime.getSeconds()<10?"0"+datetime.getSeconds():datetime.getSeconds();
return year + "-" + month + "-" + date+" "+hour+":"+minute+":"+second;
}else{
return "---";
}
