How about putting the following in your program library:

WITH Text_IO;
PACKAGE Duration_IO IS NEW Text_IO.Fixed_IO(Num=>Duration);

in subsequent programs, just "with" Duration_IO. Since Duration is
just a fixed-point type, this will work fine (I've done it before).

Keep the following in mind: if your program is running on a timesharing
system, Calendar gives REAL TIME (WALLCLOCK), not the CPU time used
by your program. (On a PC, since you're the only user, the two times
are equivalent)

I can post a Unix-oriented CPU timing package that interfaces to C,
to get CPU time from Unix timing services. Anyone interested?
