The code for the timer is already in the rom, they decided not to add the timer at nearly the last minute. The timer would not be so accurate because they did not include the crystal to control the clock speed (system clock)
I think there is a set of three buttons you can press at one time to get it in and out of timer mode though. I just don't remember what they were.
