可以处理以下格式：

    String a = "2016-11-30 17:16:00";
    String b = "2015-07-13 11:11:22.02";
    String c = "1394438072";
    String d = "Jul 26, 2017 2:27:13 PM";
    String e = "2019-03-31";
    String g = "2019-04-01 03:13";
    String h = "1584516482676";
    String i = "2014-06-27T08:11:07.168Z";
    String j = "Tue Jan 14 16:11:26 +0800 2020";
