function js_strto_times(str_time){  
    var new_str = str_time.replace(/:/g,"-");  
    new_str = new_str.replace(/ /g,"-");  
    var arr = new_str.split("-");  
    var datum = new Date(Date.UTC(arr[0],arr[1]-1,arr[2],arr[3]-8,arr[4]));  
    return strtotime = datum.getTime();
} 
function  formatDate(dateTimeStamp){
    var date = js_strto_times(dateTimeStamp);
    var commondate = dateTimeStamp;
    var now = new Date().getTime();
    //console.log(now);
    var diffValue = now - date;
    var monthC =diffValue/month;
    var weekC =diffValue/(7*day);
    var dayC =diffValue/day;
    var hourC =diffValue/hour;
    var minC =diffValue/minute;
    if(dayC>=1){
        result=commondate;
    }
    else if(hourC>=1){
        if(hourC >=10){
            result = commondate;
        }else{
        result=parseInt(hourC) +"个小时前";
        }
    }
    else if(minC>=1){
        result=parseInt(minC) +"分钟前";
    }else
    result="刚刚";
