You're probably using rails. Ruby used to *not* have a Time#to_date 
method but now it has one which is private. And the to_date helper added 
by rails is further up the call chain and therefore gets hidden by the 
private method, so that's what you get. :-/

Add one of the following in your environment.rb:
   class Time; public :to_date ;end #use the ruby-1.8.6 version
   class Time; remove_method :to_date ;end #use the rails version
