Can anybody help here ?
Just as a clue, the post is an array of informations that contains strings only.
'09:00' is a string. Joomla has to decode it with the JDate() class to transform it in a datetime object.
At this point fo example if you give '09-00' maybe JDate() don't understand.
TODO :
Understand what type of strings is waited by JDate().
convert your string to the right one.
Maybe : 0000-00-00 09:00:00 ...
For the moment, Cook doesn't handle time format.
So if you want it you should have changed some dates format.
I really do my best to improve everyday the soft, but in this case you have to try to solve it with the help of others users.
Model-View-Controller is the basis you have to understand if you want to modify the source code and post in this category.
