Java Timing Library

Question

I'm looking for something in JodaTime or similar which will let me obtain a Duration from a string passed in.

My string will look like: "00:04:23" (HH:MM:SS) I'd like to be able to get that converted to other time units easily.

Unfortunately Duration.parse() from JodaTime doesn't work. Is there another method which would do this, or do I need to roll my own?

As requested some examples:

01:34:22 -> 1 hour 34 minutes and 22 seconds
00:04:23 -> 4 minutes and 23 seconds
00:00:46 -> 46 seconds

It's easy to roll own, but was curious if there was a built in for that, which I was just missing.

Can you provide some sample inputs and a desired result or output? — Freiheit

You mean you want human-readable strings, but ones that can be trivially created using a split, parse, and sprintf? — Dave Newton

I'm still pretty new to JodaTime, but using PeriodFormatterBuilder to obtain a Period and then converting it to a Duration seemed to work for me:

String input = "12:14:02"; ReadWritablePeriod period = new MutablePeriod(); new PeriodFormatterBuilder() .appendHours().appendSeparator(":") .appendMinutes().appendSeparator(":") .appendSeconds().toParser().parseInto(period, input, 0, null); Duration duration = period.toPeriod().toStandardDuration();

I'm not sure what the impact of a null Locale is here.
