一 时间格式化输出
3个M 表示输出月份单词
DateTime now =new DateTime();
System.out.println(now.toString("yyyy-MM-dd HH:mm:ss")); //2019-06-26 17:02:15
System.out.println(now.toString("yyyy-MMM-dd hh:mm:ss a")); //2019-六月-26 05:02:15 下午
System.out.println(a.toString("yyyy-MMM-dd hh:mm:ss a", Locale.US));//2019-Jun-26 05:03:47 PM
二 任意格式时间转时间戳
String time="2019-Jun-26 06:00:00 pm";
DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MMM-dd hh:mm:ss a").withLocale(Locale.US);
DateTime dateTime = DateTime.parse(time, format);
System.out.println(dateTime.getMillis()); //1561543200000
