public static String getDistanceTime(long  time1,long time2 ) {
    long day = 0;
    long hour = 0;
    long min = 0;
    long sec = 0;
    long diff ;
    String flag;
    if(time1<time2) {

        flag="前";
    } else {
        diff = time1 - time2;
        flag="后";
    }
    day = diff / (24 * 60 * 60 * 1000);
    hour = (diff / (60 * 60 * 1000) - day * 24);
    min = ((diff / (60 * 1000)) - day * 24 * 60 - hour * 60);
    sec = (diff/1000-day*24*60*60-hour*60*60-min*60);
    if(day!=0)return day+"天"+flag;
    if(hour!=0)return hour+"小时"+flag;
    if(min!=0)return min+"分钟"+flag;
    return "刚刚";
