I'm glad to see this cleanup. I think it is worth explaining a bit more,
though, why this hunk in particular:

the parameters that are being deleted. Maybe something like:

  Commit b841d4ff43 (Add `human` format to test-tool, 2019-01-28) added
  a get_time() function which allows $GIT_TEST_DATE_NOW in the
  environment to override the current time. So we no longer need to
  interpret that variable in cmd__date().

  Likewise, we can stop passing the "now" parameter down through the
  date functions, since nobody uses them. Note that we do need to make
  sure all of the previous callers that took a "now" parameter are
  correctly using get_time().

which I think explains all of the hunks.
