According to GP 2.1.1 Specification

Why is it?

Create a Supplementary Security Domain

I want to create a Supplementary Security Domain, but I don't know how.
Do I have to create an applet which implements Secure Channel, and then install the applet with the privileges 0x80? Am I right?

access the CPU timer inside a Java card Applet,

For JavaCard 3, As far as I know, it seems to be possible to access the CPU timer inside a Java card Applet, since the method System.getCurrentMillis() is available. But Is it possible for Javacard 2 either?
Are there any Javacards with proprietary extensions that allow to access a timer?
