Hi Erick
I''ve done that using  application helpers 
(app/helpers/application_helper.rb)
so that you can spread them in yr code and, if you need to change the 
format,
you do just it  in one place.
You can use them as <%= mydate(customer.created_on) %> for example.
def mydate(d)
  d.strftime("%d/%m/%y")
end
def mytime(d)
  d.strftime("%H:%M")
end
def mydatetime(d)
  d.strftime("%d/%m/%y %H:%M")
end
Cheers,
Andre

And what about changing the default display format for time values?
