如何显示sensorevent.timestamp for Android的准确时间？

public void onSensorChanged(SensorEvent event) {
    long currentTimeMillis = System.currentTimeMillis();
    long sensorTimestampMillis = event.timestamp / 1000000; // 将纳秒级时间戳转换为毫秒级时间戳

    Date currentDate = new Date(currentTimeMillis);
    Date sensorDate = new Date(sensorTimestampMillis);

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    String currentTime = dateFormat.format(currentDate);
    String sensorTime = dateFormat.format(sensorDate);

    Log.d("Timestamp", "Current Time: " + currentTime);
    Log.d("Timestamp", "Sensor Time: " + sensorTime);
}
