    Make git-committer inferred version-date TZ-invariant · bab51097
    Herbert Valerio Riedel authored
    The existing code suffers from the issue of converting the
    committer date to localtime, thereby resulting in varying
    inferred dates for the same commit-hash depending on the currently
    set local timezone.
    
    In order to have a universally unique mapping between commit-hashes and
    their snapshot-version-date it's better to convert to the date expressed
    in a fixed timezone like e.g. UTC.
    
    Sadly, `git` doesn't seem to provide a way to directly format dates the
    way we need it, so we shell out to `perl` for this.
