If it does not have to be really accurate, use a loop to check the clock
counter at location 0x46c (4 bytes counter) until it advances 9 times.
This method has the accuracy of within 1/18 of a second.

A more accurate method is to write a counting loop to count how many times
does it loop when the clock counter advance from x to x+1 and use the
loop count as a timing base for a timing loop which take the same number
of cycles to loop once as the initial counting loop. Yes, this implies
intimate knowledge of the code generated by the compiler or write both
loops in assembler (can be easily done in TC).
