[svn-r4698] 
Purpose:
	Bug Fix
Description:
	Fixed so that it will display the correct timing data. It will also
	write to the correct file (which it wasn't before).
Solution:
	Put the code in for displaying the time. Had to change the way I was
	passing an object to the pio_fopen() function from just being a
	structure to being a pointer so that the changes could be propagated
	back.
Platforms tested:
	Linux
