** Source: GetFileTime.c
**
** Purpose: Tests the PAL implementation of the GetFileTime function.
** This test checks the time of a file, writes to it, then checks the
** time again to ensure that write time has increased. It
** also checks that creation time is the same under WIN32 and has
** increased under FreeBSD.
**
** Depends:
** CreateFile
** WriteFile
** CloseHandle
