// 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.

//
