--  This package provides target machine specific Clock related definitions.
--  Portability of System.Task_Clock package is accomplished separating
--  this child package out. We only need to modify this package for
--  different targets.

--  This version of Clock uses the time() function, which is available
--  in most C libraries.  This is the "universal" version; it is
--  only accurate to 1 second and is not the same time base used by
--  the tasking library System.Real_Time.Clock and delays, but will
--  work on systems without tasking or POSIX.

--  This is a dummy version of this package (no tasking support).
