+// 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.
+//
