美国服务器计算时间有时间差 1小时

//beginDate = '2013-03-06 00:00:00'
//endDate = '2013-03-08 00:00:00'
	public static int intervalDay(String beginDate,String endDate){
		DateFormat dfs1 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		DateFormat dfs2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		Date begin = null;
		Date end = null;
		try {
			begin = dfs1.parse(beginDate);
			end = dfs2.parse(endDate);
		} catch (ParseException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		long a = end.getTime()/1000;
                //美国时间 end.getTime() 1363615810000 || '2013-03-18 12:00:00'

		long b = begin.getTime()/1000;
                //美国时间 begin.getTime() 1362546000000 || '2013-03-06 13:00:00'

		long between = (a-b);//除以1000是为了转换成秒
		int day = (int) (between/(24*3600));
		return day;
	}

中国计算时间间隔应该是12
美国计算出来的为11

        long between = (a-b);//不要除以1000，以免带来舍入误差
        int day = (int) (between/(24*3600*1000)); 

除以1000是为了计算秒，跟时间差没有关系
