git doesn't preserve file timestamps of versioned files, these get
whatever timestamp is current when being checked out. That's supposed to
be a feature. This can be problematic if some versioned files could also
be recreated by a Make-using build system: If the repository is large
enough or happens at a 'bad' time, the source files may end up being
newer than the generated files.
