That's great.  We always need help with errors in the docs so let us know
anything you find that's wrong or unclear.

Yes, swish can't parse dates.  The values should be a timestamp (seconds
since the Epoch).

So you have three choices:

1) modify your source docs to have a time stamp
2) use a filter to parse and rewrite your docs
3) use -S prog and write a program to fetch and parse your docs and convert
the dates.

A filter is easier to write, but -S prog is faster.  There's a few examples
of how to fetch docs in the prog-bin directory.

You might need to install the Date::Calc module.  That would prevent the
DateRanges module from being loaded.  You should have seen an error message
as such in the web server log.
