Master Branch

It appears you are working in the "master" branch in git. You should really be working in a version specific branch. The most direct documentation on this is Moving from a master branch to a version branch. For additional resources please see the documentation about release naming conventions and creating a branch in git.

Hey there
Integration
It seems like the module itself needs more work to be useful to drupal developers, it just provides an empty test menu entry.
How did you think to integrate those external libs with drupal itself?

Licensing
Next, i think you should provide a license (GPL compliant) to the external libraries. See http://drupal.org/licensing/faq.
Furthermore (but this is just for my personal knowledge), what the gdate library is supposed to add to standard php DateTime functions?

Code lenght requirements
Finally, check code length requirements: lower bound is 120 lines, i think this limit is apart from external libs.
From http://drupal.org/node/1011698:

Note: Your project should include at least ~120 lines of custom code and ~5 custom functions to receive a proper review. This will help demonstrate your understanding of writing secure code, following the coding standards, generally following best practices and familiarity with proper usage of the Drupal APIs.

Closing due to lack of activity. Feel free to reopen if you are still working on this application.
