[android-developers] issues with opensource project AndroidGlobalTime

I'm using Android 4.0.3 , downloaded a open sorce project
'AndroidGlobalTime' ,
after importing code into my eclipse workbench it's showing error for
two classes..

import android.opengl.Object3D;
import android.pim.DateUtils;

is these packages are available with any android version ?

i found Object3D class in
http://code.google.com/p/netthreads-for-android/source/browse/trunk/bulletml/src/com/netthreads/android/opengl/Object3D.java?r=17
i tried to add this class to my project but it looking some other
dependent classes !!

the above two classes are is the part of the SDK ?
