lynx-dev dev.17 patch 1 - FTP times

[Klaus Weide]

* Date calculations for file times in FTP directory listings used cached
  values for the current day and year that never got reset.  This could
  cause wrong ordering when sorting by date, and possibly other errors,
  especially in long-running lynx sessions.  Now recalculate them for each
  new directory request if they are needed.
* Be slightly more tolerant about FTP directory listing file times that
  appear to lie in the future: allow today plus one day without assuming
  that it must mean a year ago, to account for possible timezone differences.
