时间戳转为年月日时分秒格式

1、小于10前面补0 

function add0(m){
     return m<10?'0'+m:m 
 }

2、转为年-月-日  时:分:秒格式

function timeFormat(ts)
{
  var time = new Date(ts);
  var y = time.getFullYear();
  var m = time.getMonth()+1;
  var d = time.getDate();
  var h = time.getHours();
  var mm = time.getMinutes();
  var s = time.getSeconds();
  return y+'-'+add0(m)+'-'+add0(d)+' '+add0(h)+':'+add0(mm)+':'+add0(s);
}
