如何僅從 Google Apps 腳本中的 getDate() 獲取時間？

Question

我正在嘗試在 Google Apps Script 中創建一個基於時間的過濾器，以在一天中的特定時間過濾掉來自我的 gmail 帳戶的具有特定主題行的郵件，並將標簽應用於這些郵件。
到目前為止，我已經按主題行隔離了郵件，現在我想使用時間進一步隔離它們。 到目前為止，這是我的代碼：

function xyz_filter() {
  var sent_threads = GmailApp.search('subject:xyz');
  Logger.log(sent_threads.length);
  for (var i = 0; i < sent_threads.length; i++) {
    var message = sent_threads[i].getMessages()[0];
    var recipient = message.getDate();
    Logger.log(recipient);
  }
}

我對 Google Apps Script 還很陌生，在過去的幾個小時里，我一直在尋找類似用例的stackoverflow 。
我的代碼主要取自這個鏈接： GMailApp Gmail 搜索

這是日志的輸出：

請提出一種僅從該輸出中獲取時間的方法。

Answer 1

您是否嘗試過使用： recipient.getHours(); recipient.getMinutes(); recipient.getSeconds(); recipient.getHours(); recipient.getMinutes(); recipient.getSeconds(); 收件者需要幾個小時，幾分鍾和幾秒鍾的時間。

在這里，您將找到有關如何使用它的更多信息https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date 。 我希望能有所幫助，問候。

Answer 2

嘗試 :recipient.toTimeString() 這會給你“00:01:48 GMT+05:30”，下面的代碼將有助於獲得像“00:01:48”這樣的時間

function CreatTimestring(str1,pos){
    var str2='';
    for (var i=0;i<pos-1;i++){
      str2+=str1[i];
    }
    return str2;
  }
TimeStr = CreatTimestring(recipient.toTimeString(),recipient.toTimeString().indexOf('G',0));

希望這會幫助其他人..
