I will assume you mean Ada 83...

No. You will have to make system calls. The correct calls depand upon
what platform/OS/compiler you have.

However, it sounds to me like what you want is a performance analyzer.
Most good development systems come with one. They work much like a 
debugger, but merely log information and continue, rather than stopping
at their "trace points". Check you vendor/O.S. documentation to see
if you have one. Most come set up to automaticly collect data on the
amount of time spent in each routine/program block.
