Countdown Timer using seconds and milliseconds

Countdown Timer using seconds and milliseconds

The goal of my timer is to:
Allow the user to count down from three pre-set times: 15secs, 30 secs, 60
secs The timer will count down to 00:00 and stops. The user can at any
time stop/start time or move countdown to new countdown time.
I have been able to do all of the above except for resetting the countdown
timer when it reaches 00:00. The problem is that when timer hits 00:00 it
no longer correctly starts the timer with the users new choice in time.
(The project is setup over nibs and has references to outlets belonging to
that nib).

Any help would be great.
