Timestamp 时间比较

       Timestamp from_time = BzUtils.parseUTCDateTime("2020-03-05 10:37:28");
        Timestamp t1 = BzUtils.parseUTCDateTime("2020-03-05 10:37:28");
        Timestamp t2 = BzUtils.parseUTCDateTime("2020-03-05 10:37:29");
        Timestamp t3 = BzUtils.parseUTCDateTime("2020-03-05 10:37:30");
        System.out.println(t1.compareTo(t2));
        System.out.println(t2.compareTo(t3));
        System.out.println(t3.compareTo(t1));
        System.out.println(from_time.compareTo(t1));

判断大于等于0或者小于等于就可以
