Hi James,

if you want to implement the timing inside your code,
you could also use the system library `Time`

http://www-ps.informatik.uni-kiel.de/kics2/lib/Time.html

which provides access to current clock time etc.
However, one has to be careful w.r.t. lazy evaluation
so that you really time the right things.
Thus, the method described by Sandra is usually the
preferred one.

Best regards,

Michael
