Issue with Date class monkey patching.

[manpreetnarang]

Adding runt to the rails app causes the (-) overloaded operator to behave differently. Here's an example:

Without runt:
:001 > Date.today
=> Thu, 09 Apr 2015
:002 > Date.today - 1.day
=> Wed, 08 Apr 2015

After requiring runt:
:001 > Date.today - 1.day
=> Fri, 18 Sep 1778

Hi everyone,

This was just a mirror repo... I didn't originally write runt, but I'd be happy to accept patches into this repo if someone wants to make a pull request.
