Php 如何在vcalendar中处理日光和标准时间之间的切换？

生成的代码仅在当前时区（白天或标准时间）有效。当我将会议Outlook从标准时间发送到白天或从标准时间发送到白天时，Outlook会更正会议并将其向前移动1小时

Outlook按如下方式更正它： 此会议是根据您当前的时区自定义的。最初创建于这个时区：欧洲/布拉格

我发送会议-2020年5月6日：上午8-9点 但展望2020年5月6日上午9点至10点

Outlook或我的代码中是否存在问题？ 谢谢你的帮助

这是php（7）中的脚本，用于从特定xml源收集数据。我需要将它们发送到outlook日历中。我们正在使用outlook 2016和365

    function setICalendar(){
  $this->strICalendarClass="\nBEGIN:VCALENDAR\nMETHOD:REQUEST";
  $this->strICalendarClass.="\nBEGIN:VTIMEZONE\nTZID:Europe/Prague";
  $this->strICalendarClass.="\nX-LIC-LOCATION:Europe/Prague";
  $this->strICalendarClass.="\nBEGIN:STANDARD";
  $this->strICalendarClass.="\nDTSTART:19411001T000000";
  $this->strICalendarClass.="\nTZOFFSETFROM:0000\nTZOFFSETTO:0000\nTZNAME:Standard Time";
  $this->strICalendarClass.="\nRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=10";
  $this->strICalendarClass.="\nCET";

  $this->strICalendarClass.="\nRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=3";
  $this->strICalendarClass.="\nCEST";
  $this->strICalendarClass.="\nEND:DAYLIGHT\nEND:VTIMEZONE";
  $this->strVEvent="\nBEGIN:VEVENT";

nBEGIN:VCALENDAR
METHOD:REQUEST;

X-LIC-LOCATION:Europe/Prague;

我希望在开始阶段和展望阶段都能有同样的时间。

我修复了它，就像这样，一切都正常
