[PATCH] date: return failure exit code on set time error

[Ladislav Michl]

Gentle ping... Not possible to do any reasonable scripting as date
claims to be successfull all the time.

Coreutils-8.32 date does:

      if (set_date)
        {
          /* Set the system clock to the specified date, then regardless of
             the success of that operation, format and print that date.  */
          if (settime (&when) != 0)
            {
              error (0, errno, _("cannot set date"));
              ok = false;
            }
        }
[snip]
  return ok ? EXIT_SUCCESS : EXIT_FAILURE;
