I'm trying to get the timetextbox and datetextbox up and running on an existing platform, and I'm stuck. My system already accepts mm-dd-yyyy formating (and I worked that out with serialize:) but it also pre-fills with the same format. The problem is dojo will only accept yyyy-mm-dd as a valid format:

However, you must provide numbers and dates from the server in JavaScript format. This goes for the value property and the min and max constraint values. You may do the conversion at the server or through the dojo.getXhr callback.
