Description

The current output of build times is hard to read and does not follow any standard. I have patched branch 2.2.x and 3 trunk to follow ISO 8601-style date/time formats.

My patches need less code compared to the current solution. I had the following ideas in mind:

1. Display times in the same proportional format.
2. hour display is fixed to max 24 h as in ISO defined.
3. Days are directly integrated, not brain math necessary anymore. Though this should be a rare case.
3. remove the smallest component if a bigger one is added.
4. Easier to parse, predictable output.

More over, I have changed the finish and total time to ISO too. I did not touch the finish time in Maven 2.2.x because it is alphanumeric. I'd rather prefer that as total time but this is maybe a matter of taste and harder to parse.

This is a real output:

A crafted output with all formats would look like this:

Since most build are below an hour, they are way easier to read.
