        Timer : LongInt Absolute $0040:$006c;

    That's the Tic counter, stored at Segment 0040h, offset 006Ch. It
stores the number of ticks since you turned the Computer on and so will
only wrap after MorE THAN 3 YEARS, if you never close the machine ;-)

    it is incremented 18.2 times/sec, so divide it by 18.2 to get the
number of seconds. You can figure out the rest ;-)

    Store its content to another LongInt at the start of the Program,
again at the end. Substract the first value from the second and you have
the number of ticks elapsed during the Program's execution.

Oh what the heck, here is a Complete Unit, all you have to do is include
it in your Uses clause nothing more unless you want to save the time in
a log File or something.
