以编程方式设置安卓的日期/时间

我需要以编程方式从Android设置日期/时间,但我没有成功!我上面有这三个来源:
源代码 1
AlarmManager alarm = (AlarmManager) getSystemService(ALARM_SERVICE);
alarm.setTime(1330082817000);
AndroidManifest:
<uses-permission android:name="android.permission.SET_TIME" />
<uses-permission android:name="android.permission.SET_TIME_ZONE" />
例外:
Service fatal error : Unable to start activity ComponentInfo{br.com.tdta.service/br.com.tdta.service.Service}: java.lang.SecurityException: setTime: Neither user 10038 nor current process has android.permission.SET_TIME.
java.lang.RuntimeException: Unable to start activity ComponentInfo{br.com.tdta.service/br.com.tdta.service.Service}: java.lang.SecurityException: setTime: Neither user 10038 nor current process has android.permission.SET_TIME.

源代码 2
boolean itsWork = SystemClock.setCurrentTimeMillis(1330082817000);
System.out.println(itsWork);
清单:
<uses-permission android:name="android.permission.SET_TIME" />
<uses-permission android:name="android.permission.SET_TIME_ZONE" />
其工作价值:
false

源代码 3
SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd.hhmmss");
String data = format.format(new Date(1330082817000));
try {
Runtime.getRuntime().exec("date -s " + data);
} catch (IOException e) {
}
我做错了什么?
提前致谢!
