Re: [PATCH v3 5/6] date: document and test "raw-local" mode

I do find this by itself a little hard to parse. Maybe:

  `--date=raw` shows the date as seconds since the epoch (1970-01-01
  00:00:00 UTC), followed by a space, and then the timezone as an offset
  from UTC (a `+` or `-` with four digits; the first two are hours, and
  the second two are minutes). I.e., as if the timestamp were formatted
  with `strftime("%s %z")`).

I also had trouble with what I wrote.  Thanks for a great help.
