我有一个 Discord.js 机器人，它使用外部 API 检索祈祷时间并为这些时间设置提醒。该机器人在我的本地主机上运行良好，其中时区设置为本地主机上的埃及开罗。但是，当我将机器人部署到 Repl.it 或 Render 等托管环境时，我注意到机器人输出中显示的时间存在差异。 其中命令中设置的时区比当前时区多 3 小时。
这是我的代码：

我已经验证我正在使用 Moment.js 和 Moment Timezone 库在代码中正确处理时区。 日期、nextPray 持续时间在服务器上不正确，在本地主机上正确，但下一个祈祷旁边的下一个祈祷字符串在本地主机和服务器主机上都可以正常工作。
Date
构造函数调用，通过
new Date()进行调用，然后是
getTime()。这意味着结果将被解释为从 1970 年 1 月 1 日到该日期的毫秒数，但是
该日期将基于环境区域设置。
假设你有这个：
console.log(new Date(2013, 1, 1, 1, 1).getTime())
在具有 Europe/London
语言环境的环境中，此返回
1359680460000。在
America/Montreal语言环境中，返回
1359698460000。相差5个小时。如果您提取的日期采用 UTC 格式，则应使用 构造函数。 如果它们位于另一个时区，您可以使用
moment.tz()
来正确摄取它们。
