No, you have misunderstood.

The *date* command, as shown, is a unix system command. But dateutils
is not.

The relevant lines from the demo code are:

import commands
now = parse(commands.getoutput("date"))

which uses the commands module to send the command "date" to the
operating system, run it, and get the result, and only then gets
dateutil to parse the text.

You can replace those lines with:

now = parse("Fri Oct 19 13:16:40 EST 2012")

and I expect it will work.

Have you tried running `date` at the Windows command.com (or cmd.exe,
or something, I never remember which)? What does it print?

My guess is that it probably prints something like:

"Command not found"

which clearly cannot be parsed as a date.
