2 questions: End level score tally, and keep time.

I'm wonder how I would keep time on how long you're playing the level. Take this for example from Sonic 1:

And how would I make the score add up to how long you've been playing and how many rings you have at the end? Like this:

Make a global variable named timer

Make a global variable Time Bonus and set it to the amount of seconds the level should take.

system every 1 second add one to timer

set text - "Time: "&Floor(Timer/60) & ":" & right("00"&Floor(Timer%60),2)

at the end of the level:

system comape two values : time bonus-timer > 0 - add something to score.
