[Seaside] Controlling value returned from Canvas' dateInput

[Rick Flower]

I just started using the dateInput "widget" (or whatever you call it).. 
It currently returns a string such as "February 17, 2007", but I am 
wondering if it can be configured to return something else such as a 
Date object or perhaps a timestamp.. I guess in the meantime I could 
parse the returned string and call the "newDay:month:year" object 
creation routine for the Date object to get back a date stamp or 
timestamp...  Comments?
