** Test to see that access date either stays the same or increases
** when a read is performed. Write
** and creation time should stay unchanged. Note: Under FreeBSD
** the Creation time should not change with just a read.
**
** Depends:
** FileTimeToDosDateTime
** CreateFile
** ReadFile
** CloseHandle
