+**  CONVTIME -- convert time
+**
+**	Takes a time as an ascii string with a trailing character
+**	giving units:
+**	  s -- seconds
+**	  m -- minutes
+**	  h -- hours
+**	  d -- days (default)
+**	  w -- weeks
+**	For example, "3d12h" is three and a half days.
+**
+**	Parameters:
+**		p -- pointer to ascii time.
+**		units -- default units if none specified.
+**
+**	Returns:
+**		time in seconds.
+**
+**	Side Effects:
+**		none.
