Php 在不同时区打开时无法使vCalendar（vcs）进行时间调整

Php 在不同时区打开时无法使vCalendar（vcs）进行时间调整,php,vcalendar,Php,Vcalendar,我正在使用iCalcreator（v2.6）PHP库创建一个.vcs文件。在Outlook（最新版本，我不知道其他版本）中打开活动时，会议日期/时间不会调整为本地时间。我认为这可能与有关，但设置X-MICROSOFT-CDO-TZID值似乎没有帮助。我希望有人知道一些关于vcs文件创建谁可以告诉我在正确的方向。以下是我正在创建的vcs文件： BEGIN:VCALENDAR CALSCALE:GREGORIAN METHOD:PUBLISH PRODID:-//127.0.53.53//NONSG

几年过去了，但这是我的工作方式，也许这会帮助其他任何遇到这个问题的人

我从来没有尝试过TZOFFSETFROM…所以不确定这是关于什么，甚至不知道它是否有效。但是，如果将时区放在DTSTART和DTEND中，它将自动调整。您只需要将日期设置为UTC格式，就像上次修改的日期一样。我这样做（

$start

和

$end

是PHP日期时间对象）：

因此，基本上，所做的就是将日期放入UTC时区，然后在末尾用Z格式化日期/时间，以将其传达给客户机

一个完整的工作示例（如果对任何人都有帮助）是：


"DTSTART:".$start->setTimezone(new DateTimeZone('UTC'))->format('Ymd\THis\Z').$eol.
"DTEND:".$end->setTimezone(new DateTimeZone('UTC'))->format('Ymd\THis\Z')
