Description

creating an archive in a Reproducible Builds way requires to configure archiver with an output timestamp: see https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=74682318

The timestamp value can't be natively injected as Date with Plexus, because Plexus Date injection uses local timezone, then is not reproducible: see https://codehaus-plexus.github.io/plexus-containers/plexus-container-default/xref/org/codehaus/plexus/component/configurator/converters/basic/DateConverter.html

Then we need top inject ${project.build.outputTimestamp} as a String and provide an API to parse this String to a Date, before calling plexus-archiver's configureReproducible https://github.com/codehaus-plexus/plexus-archiver/pull/121
