Subject: [PATCH] Time: add 'ddate' (#1310)

* Time: add 'ddate', fix contributors, add Time.local as a package_dir in setup.py

* Time: add in license information for ddate.py

* Time: change 'ddate' command to where it will error out gracefully if 'ddate.base' isn't available

* Time: add tests, remove Time.local from package_dir
