File Info's dates come from the clock, so documents made or saved a second
apart differed: journal_replay_reproduces_document and
rich_fixture_satisfies_invariants_and_undoes_to_blank failed at random.
One approach for every clock-derived date: it is a command input that
defaults to now, and the journal records the value used.
- file.new takes created? and document.save / file.saveAs take modified?
(Unix seconds, or null for none; default now), through date_param /
clock_date on the one save path (save_with), so Save, Save As and the
UI's save stamp alike; Save a Copy still leaves the dates.
- Their journal entries always record the date used, so replaying the
journal makes the same document whenever it runs. Actions recorded from
the journal (Session::journal_for_action) leave those dates out, so
playing an action later dates the document then.
- Test fixtures date their documents fixtures::CREATED, and the MCP
property test dates its local document as the headless one, so
documents built at different moments compare equal.
