-This code uses the <code>Dates</code> module, which is being incorporated into Julian's standard library with the current development version (<tt>0.4</tt>).  I've used <code>isdefined</code> to make this code good for the current stable version (<tt>0.3</tt>) as well as for future releases.  If <code>Dates</code> is not installed on your instance of Julian try <code>Pkg.add("Dates")</code> from the <tt>REPL</tt>.
