Print build times in an ISO8601-style manner
--------------------------------------------
Key: MNG-5176
URL: https://jira.codehaus.org/browse/MNG-5176
Project: Maven 2 & 3
Issue Type: Improvement
Components: Logging
Affects Versions: 3.0.3, 2.2.1
Environment: Maven 2.2.1 and 3.0.3
Reporter: Michael Osipov
Attachments: 2.2.1.patch, 3.0.3.patch
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 ISO8601-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.
