Christian Jung commented on MNG-5623:
-------------------------------------
[~michael-o] Its currently not possible for me to run any commands on the build
servers, but i found a simpler way to reproduce the error:
With the following simple script i reset the time every few seconds:
{code:timewarp.sh}
#!/bin/bash
while true; do
date +%T -s "10:13:13"
sleep 5
date
done
{code}
This produces negative durations in maven. The output is then:
{code}

It seems that time does not display any negative times.

> {code}

> However, in {{formatDuration}}, from {{CLIReportingUtils.java}} , it seems
> that the generated strings can well exceed this length:
> {code}
> 177: format = "%d d %02d:%02d h";
> {code}
> This has, as far as I understand, at least 6 characters, if we add two for
> minutes and minimum one for hour and one for day, this will already exceed
> the BUILD_TIME:DURATION_LENGTH. This seems an obvious bug to me.
> However our build times are usually less than one hour, so there must be some
> other reason for our strange long build time duration string.
> If the bug above was fixed, we could see better what's going on.
