Question

我目前正在将一些c ++代码移植到ruby，我从zabbix返回一个日期值，它返回日期原语。

目前执行此操作的代码是：

private static final long SPLASH_DURATION = 2*1000; private long mStartTimestamp; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.your_layout); mStartTimestamp = System.currentTimeMillis(); new MyTask().execute(); } class MyTask extends AsyncTask<Void, Void, Boolean>{ @Override protected Boolean doInBackground(Void... params) { // your logic here return true; } @Override protected void onPostExecute(Boolean success) { super.onPostExecute(success); // check your result here if(success){ long timeStop = System.currentTimeMillis(); long delta = timeStop - mStartTimestamp; if (delta >= SPLASH_DURATION) { startMainActivity(); } else { new Handler().postDelayed(new Runnable() { @Override public void run() { startMainActivity(); } }, SPLASH_DURATION - delta); } } else { // handle the error } } }

到目前为止我得到了这个：

Math.round(((new Date().valueOf()) - parseInt(result[0].value) * 1000) / 86400000)

不确定如何移植(result[0]['value'].to_i*1000) / 86400000).round

1441972284808看起来像Unix时间戳，以毫秒为单位，所以你可以试试这个：

time = Time.at(1441972284808 / 1000.0)
# => 2015-09-11 16:51:24 +0500
time.strftime('%j') # days quantity from start of the year
# => "254"

将Date.valueof原语转换为Ruby
