获取当前系统时间,设置系统时间

            SimpleDateFormat formatter = new SimpleDateFormat(                    "yyyy年MM月dd日 HH时:mm分:ss秒");            Date curDate = new Date(System.currentTimeMillis());// 获取当前时间            String str = formatter.format(curDate);

    static void setTime(Context context, int hourOfDay, int minute) {                  Calendar c = Calendar.getInstance();                  c.set(Calendar.YEAR,2015 );                  c.set(Calendar.MONTH,5 );                  c.set(Calendar.DAY_OF_MONTH,8 );                  c.set(Calendar.HOUR_OF_DAY, 3);                  c.set(Calendar.MINUTE, 42);                  c.set(Calendar.SECOND, 0);                  c.set(Calendar.MILLISECOND, 0);                  long when = c.getTimeInMillis();                        if (when / 1000 < Integer.MAX_VALUE) {                    //((AlarmManager) context.getSystemService(Context.ALARM_SERVICE)).setTime(when);                    SystemClock.setCurrentTimeMillis(when);
