在 Java/Groovy 中计算经过的时间 [英] Calculate elapsed time in Java / Groovy

问题描述

我有...

Date start = new Date()

...
...
...

Date stop = new Date()

我想获得这两个日期之间经过的年、月、日、小时、分钟和秒.

I'd like to get the years, months, days, hours, minutes and seconds ellapsed between these two dates.

我会细化这个问题.

我只想得到经过的时间，作为一个绝对的度量，即不考虑闰年、每个月的天数等.

I just want to get the elapsed time, as an absolute measure, that is without taking into account leap years, the days of each month, etc.

因此我认为不可能过去几年和几个月，我只能得到几天、几小时、几分钟和几秒钟.

Thus I think it's impossible to get the years and months elapsed, all I can get is days, hours, minutes and seconds.

更具体地说，我想说明某项任务持续了例如

More specifically I want to tell that a certain task lasted for e.g.

20 sec
13 min, 4 sec
2 h, 10 min, 2 sec
4 d, 4 h, 2 min, 2 sec

所以请原谅我不够精确.

So please forgive my lack of precision.

推荐答案

我刚刚发现了这个源自 Groovy 的快速解决方案:

I've just discovered this quick Groovy-sourced solution:

import groovy.time.TimeCategory 
import groovy.time.TimeDuration

Date start = new Date()

// do something here

Date stop = new Date()

TimeDuration td = TimeCategory.minus( stop, start )
println td
