- * Description:
- *	This header file is the autoconf replacement for time.h (if it lives
- *	on the system).
- *
- *	The added benefit of this header file is that it removes the
- *	"time with sys/time" problem.
- *
- *	According to the autoconf manual, some systems have a sys/time.h that
- *	includes time.h, but time.h is not written to handle multiple
- *	inclusion.  This means that a program including sys/time.h cannot
- *	also include time.h.
- *
- *	This header file fixes that problem.
