Updating json file with "leap year dates" still has issue

[jylow]

Previous issue was fixed with the leap year date thing. However, when json file is changed to include 31-02-2001 or any such not allowed dates, the system still allows parsing and sets the date at the closest date before.

Conversely, changing date to 13-13-2000 will result in an exception being thrown and the file not being able to be opened. Such an issue should be documented in the UG as well.

As mentioned, we can specify this in the UG.
