** Source: GetFileTime.c
**
** Purpose: Tests the PAL implementation of the GetFileTime function.
** Perform two reads from a file without closing until the end
** of the test and verify that only the access times change.
** Note: Under Win32, modify time changes as well so we will
** check that it doesn't go backwards
**
** Depends:
** FileTimeToDosDateTime
** CreateFile
** ReadFile
** WriteFile
** CloseHandle
