Merge pull request #37 from daniphp/master

The state for date property was not properly loaded - Thanks daniphp

Note: In the future please can you issue pull requests from a fresh branch rather than master.  This pull request actually contained both this bug fix and the fix for property set state. Pull requests are not static, i.e. if you make further updates they will also be reflected in the pull request. Hence using a clean branch for each pull request. Since in this case I already merged the other pull request I will go ahead with it anyway.

Unit tests are also helpful :)
