Google 通过 Google 脚本和网络界面执行的查询公式给出了不同的结果

Question

我需要一个解决方案来解决我的问题，即如何在 Google 脚本中获取 today and tomorrow 的日期。我在 While trying to understand the code provided in the answer I found out that I get different result from the script and from web interface. The script does not pick up one email, the one that was sent 0:49am. 中得到它请注意，脚本有 6 个线程，但 Web 界面有 7 个。

知道该怎么办吗？调试，报告？

function today_tmp() {
  const today = new Date();
  const today_2 = new Date();
  today_2.setDate(new Date().getDate()+1);
  const td = Utilities.formatDate(today, 'GMT+2', "yyyy/MM/dd");
  const td_2 = Utilities.formatDate(today_2, 'GMT+2', "yyyy/MM/dd");
  const mylabel = 'unread';
  const queryString = `label: ${mylabel} after: ${td} before: ${td_2}`;
  const threads = GmailApp.search(queryString); 
  //const threads =GmailApp.search(queryString, 0, 10);  // this one did not work
  Logger.log(queryString);
  Logger.log(threads.length);
  for (var t in threads) {
    Logger.log(threads[t].getMessages()[0].getSubject());    
  }
}

更新 GMT+1 在项目属性中设置。我试图在代码中更改 GMT+1，但它对问题没有影响。我住在布拉格时区。

getDate()“丢失”消息是 Wed Oct 21 00:49:09 GMT+02:00 2020，今天是 10 月 21 日。

经过反复试验，仅按日期搜索时，GmailApp.search 似乎与时区信息不一致（脚本项目属性与 GmailApp API 命令）。如果您需要根据您的时区非常具体地捕获日期边界，您应该将该信息作为时间戳值传递。

const mylabel = 'unread';
const morning = new Date();
morning.setHours(0, 0, 0, 0);  // Set date to midnight of current day
const night = new Date();
night.setHours(24, 0, 0, 0); // Set end date to future midnight of current day

const queryString = `label: ${mylabel} newer:${morning.getTime()/1000} older:${night.getTime()/1000}`;
const threads = GmailApp.search(queryString);
