        Description

        Currently Jar and Jmod implementation will timestamp newly created entries with the Current Time or the source file last modified timestamp.
        To enable "reproducible builds" the jar and jmod tooling need the ability to specify a "source-date" (akin to SOURCE_DATE_EPOCH standard), so that the generated content optionally has a specified "timestamp".

        This enhancement proposes the following changes:
        - jar and jmod:
          - New option: --source-date <timestamp>
              When set content entry timestamps will be set to the given <timestamp>
