why do i keep getting the error: it’s an Object that has a before and  
after method!!!

A filter must be a Symbol, Proc, Method, or object responding to  
filter, after or before.

around\_filter MyTimer.new

class MyTimer  
def initalize  
@elapsed\_time  
end  
def before(controller)  
@start\_time = Time.now  
end  
def after(controller)  
@end\_time = Time.now  
end  
def elapsed  
@elapsed\_time = @end\_time - @start\_time  
end  
end

Not an answer to your question, but you might want to look at the  
Benchmark module to provide similar functionality.
