如何计算经过的时间，从现在乔达时？

问题描述：

我需要计算从一个特定日期所经过的的时间到现在为止，并以相同的格式*上的问题，也就是显示它：

I need to calculate the time elapsed from one specific date till now and display it with the same format as * questions, i.e.:

15s ago
2min ago
2hours ago
2days ago
25th Dec 08

你知道如何与Java的 乔达时库？是否有已经实现了它一个辅助方法在那里，或者我应该写自己的算法？

Do you know how to achieve it with the Java Joda-Time library? Is there a helper method out there that already implements it, or should I write the algorithm myself?

答

要计算所用的时间与JodaTime，使用Period$c$c>.要格式化所需的人力重新presentation所用的时间，使用PeriodFormatter$c$c>您可以通过PeriodFormatterBuilder$c$c>.

To calculate the elapsed time with JodaTime, use Period. To format the elapsed time in the desired human representation, use PeriodFormatter which you can build by PeriodFormatterBuilder.

下面是一个开球例如：

DateTime myBirthDate = new DateTime(1978, 3, 26, 12, 35, 0, 0);
DateTime now = new DateTime();
Period period = new Period(myBirthDate, now);

PeriodFormatter formatter = new PeriodFormatterBuilder()
    .appendSeconds().appendSuffix(" seconds ago\n")
    .appendMinutes().appendSuffix(" minutes ago\n")
    .appendHours().appendSuffix(" hours ago\n")
    .appendDays().appendSuffix(" days ago\n")
    .appendWeeks().appendSuffix(" weeks ago\n")
    .appendMonths().appendSuffix(" months ago\n")
    .appendYears().appendSuffix(" years ago\n")
    .printZeroNever()
    .toFormatter();

String elapsed = formatter.print(period);
System.out.println(elapsed);

这版画现在


3 seconds ago
51 minutes ago
7 hours ago
6 days ago
10 months ago
31 years ago

^{（咳嗽，老了，咳）}你看，我已经花费数月甚至几年考虑以及和其配置为省略值时，这些都为零。

^{_{(Cough, old, cough)}} You see that I've taken months and years into account as well and configured it to omit the values when those are zero.
