日期时间转换秒数或者秒数转换日期和时间

日期时间转换秒数或者秒数转换日期和时间，在前端页面需要的是日期和时间，而后端保存一般需要秒数，在比较时间前后时，也需要秒数的比较，以下是参考代码：

// 把秒数转换为日期和时间
    function changeTime(time){ 
        var date = new Date(time*1000);
        var hour = date.getHours();
        var minute = date.getMinutes();
        var second = date.getSeconds();
        return date.toLocaleDateString().replace(/\//g,'-')+' '+hour+':'+minute+':'+second;
    }
    function formatTime(time, type, format){ 
      if(!time) return '';
      if(type == 'seconds') time = parseInt(time+'000');
      if(type == 'milliseconds') time = parseInt(time);
      var DateTime = new Date(time);
      var year = DateTime.getFullYear();
      var month = prevZero(DateTime.getMonth()+1, 2);
      var date = prevZero(DateTime.getDate(), 2);
      var hours = prevZero(DateTime.getHours(), 2);
      var minutes = prevZero(DateTime.getMinutes(), 2); 
      var seconds = prevZero(DateTime.getSeconds(), 2); 
      time = format.replace(/y/g, year);
      time = time.replace(/m/g, month);
      time = time.replace(/d/g, date);
      time = time.replace(/h/g, hours);
      time = time.replace(/i/g, minutes);
      time = time.replace(/s/g, seconds);
      return time;
    }
    // 前导0
    function prevZero(num, pos){ 
      num = num+'';
      var len = pos - num.length;
      for(var i=0; i<len; i++){ 
        num = '0'+num;
      }
      return num;
    }
    // 把日期和时间转换为秒数
    function changeDate(date){ 
        var time = new Date(date.replace(/-/g, '/'))
            time = Math.ceil(time.getTime() / 1000)
        return time;
    }
    // 获取时间差
    function hasTime(time1, time2, type, format){ 
      if(!time1 || !time2) return '';
      if(type == 'seconds'){ 
        time1 = parseInt(time1+'000');
        time2 = parseInt(time2+'000');
      }
      if(type == 'milliseconds'){ 
        time1 = parseInt(time1);
        time2 = parseInt(time2);
      }
      var time = time1 - time2;
      var year = parseInt(time/(1000*60*60*24*365));
      time = time - year*(1000*60*60*24*365);
      var month = parseInt(time/(1000*60*60*24*30));
      time = time - month*(1000*60*60*24*30);
      var date = parseInt(time/(1000*60*60*24));
      time = time - date*(1000*60*60*24);
      var hours = parseInt(time/(1000*60*60));
      time = time - hours*(1000*60*60);
      var minutes = parseInt(time/(1000*60));
      time = time - minutes*(1000*60);
      var seconds = parseInt(time/1000);
      time = format.replace(/y/g, year);
      time = time.replace(/m/g, month);
      time = time.replace(/d/g, date);
      time = time.replace(/h/g, hours);
      time = time.replace(/i/g, minutes);
      time = time.replace(/s/g, seconds);
      return time;
    }
