+The temporal restrictions, with_date and with_time can take 4 different value types:
+* String value
+* Date, Time, or DateTime object value
+* Proc or lambda object which may take an optional parameter being the record object
+* A symbol matching the method name in the model
 
 When an attribute value is compared to temporal restrictions, they are compared as 
 the same type as the validation method type. So using validates_date means all
-values are compared as dates.
+values are compared as dates. This s except in the case of with_time and with_date
+options which effectively force the value to validated as a datetime against the
