Datejs replacement?

[JamoCA]

I've been using Datejs and the last official release was in 2007. I've noticed that it parses dates that sugarjs doesn't support and was wondering if you wanted to extend sugar so that it could serve as a replacement.

Some Datejs tests are available here for review & comparison:

https://github.com/datejs/Datejs/blob/master/test/relative/index.js
https://github.com/datejs/Datejs/blob/master/test/relative_date_and_time/index.js

Thanks.
