Q:

Android OS 2.2 Permissions: I have absolutely no idea why this simple piece of code doesn't work.  What am I doing wrong? 

I'm just playing around with some code.  I create an Activity and simply do something like this:
long lo = currentTimeMillis();
System.out.println(lo);

lo *= 3;
System.out.println(lo);

SystemClock.setCurrentTimeMillis(lo);
System.out.println( currentTimeMillis() );

Yes, in my AndroidManifest.xml, I've added:
<uses-permission android:name="android.permission. SET_TIME"></uses-permission>
<uses-permission android:name="android.permission. SET_TIME_ZONE"></uses-permission>

Nothing changes.  The SystemClock is never reset...it just keeps on ticking. 
The error that I'm getting just says that the permission "SET_TIME" was not granted to the program.  Protection level 3. 
The permissions are there...and in the API for 2.2 it says that this feature is supported now.  I have no idea what I'm doing wrong. 
If android.content. Intent; comes into play, please explain.  I don't really understand what the idea behind intents! 
Thanks for any help! 

A:

There is a SET_TIME_ZONE permission but there's no SET_TIME permission.  Applications cannot programmatically change the system clock. 
Update
SET_TIME is available since 2.2, but can only be granted to the system process or apps signed with the system signature.
