>             Project: Maven 2 & 3
>          Issue Type: Improvement
>          Components: Logging
>    Affects Versions: 2.2.1, 3.0.3
>         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:
> {noformat}
