Thanks for your answer, I think I got it to work.

def current_tee
  current_time = Time.now
  @current_tee = Tee.find :all, :conditions => [
    "featured = true AND start_date <
''#{current_time}'' AND end_date
>= ''#{current_time}''"
  ]
end

I had also forgot '' '' before and after
''#{current_time}''.

Thanks!
