我知道这不是“它应该工作的方式”，但仍然:如果你有两个 DateTime 对象，那么减去它们的好方法是什么？将它们转换为 Date 对象？

DateTime start = new DateTime();
System.out.println(start + " - doing some stuff");

// do stuff

DateTime end = new DateTime();
Period diff = // end - start ???
System.out.println(end + " - doing some stuff took diff seconds");

Answer 1

期间有a constructor that takes two ReadableInstant instances :

Period diff = new Period(start, end);

(ReadableInstant是DateTime实现的接口(interface)，其他类也一样。)
