** Source:  SetFileTime.c
**
** Purpose: Tests the PAL implementation of the SetFileTime function.
** This test first sets a valid file time on the file which is opened.
** Then it calls GetFileTime, and compares the values.  They should
** be the same. Note: Access time isn't checked in this test.  It will
** be dealt with seperatly due to odd behaviour.
**
** Depends:
**        CreateFile
**        GetFileTime
**
