    //如果想获取当前的年月,则可以这样写(只获取时间或秒种一样):
    SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM");    
    String date=sdf.format(new java.util.Date());     
    
    //当然还有就是可以指定时区的时间(待):
    df=DateFormat.getDateTimeInstance(DateFormat.FULL,DateFormat.FULL,Locale.CHINA);  
    System.out.println(df.format(new Date()));   
    
    //获取Android系统时间是24小时制还是12小时制
