 // Description:

 // e32test\earlyextension\earlyextension.cpp

 // This is to test the registration of early extension and will do the following

 // - Constructing the static data in VariantInit0 (the main extension object)

 // - In Init3 entrypoint allocating space in Kernel Heap to store the time stamp obtained

 // calling Kern::SystemTime().

 // - Supplying one exported function to allow reading the time stamp.

 //
