Maybe you can use javascript to combine the values from your date and time 
fields into one datetime value that your model needs? Then it would have the 
property and it could be validated.

Have you tried validating the whole object instead of just the properties? 
This is an annotation on the controller action not the model. maybe you 
could then use your buildDateTime method to make sure your model validates.
