You need android.permission.SET_TIME. Use the AlarmManager via Context.getSystemService(Context.ALARM_SERVICE) method setTime().

Snippet:

Calendar cal = Calendar.getInstance();
cal.set(2014, 9, 29, 18, 19, 00);

AlarmManager am = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
am.setTime(cal.getTimeInMillis());
