    13 // Description:
    14 // e32test\earlyextension\earlyextension.cpp
    15 // This is to test the registration of early extension and will do the following
    16 // - Constructing the static data in VariantInit0 (the main extension object)
    17 // - In Init3 entrypoint allocating space in Kernel Heap to store the time stamp obtained
    18 // calling Kern::SystemTime().
    19 // - Supplying one exported function to allow reading the time stamp.
    20 //
