Led Timer Query

[sphinxifm]

i am working on a reaction timer that measures in seconds and miliseconds how long it takes for a button to be pressed after the user is told to press it. i would like to know if anyone could offer some advice on how to make the pic16f877a do this and what circuit is best to do this with( i intend to use large led segment displays to display the results). i have purchased an easypic 4 board to experiment with and the timer is the only part of the project i havent been able to finish due to my own lack of understanding. thanks in advance for any help you may offer.
