Question

在将培训人员分配给沙特阿拉伯的课程和培训人员时，我正在使用ical向其发送电子邮件事件。将电子邮件事件发送到自动添加到他们的电子邮件中的时间（用于计时）时，这与我传递给ical的时间有误，请提供建议并帮助我将时间设置为ical（我传递给ical）。

这是我使用的功能：

function sendIcalEvent($from_name, $from_address, $to_name, $to_address, $BCC_to_address, $startTime, $endTime, $subject, $description, $location, $course_title, $loc_title)
    {
        $domain = 'testdomain.com';
        $mime_boundary = "----Training Booking----".MD5(TIME());
        $headers = "From: ".$from_name." <".$from_address.">\n";
        $headers .= "Reply-To: ".$from_name." <".$from_address.">\n";
        $headers .= "MIME-Version: 1.0\n";
        $headers .= "Content-Type: multipart/alternative; boundary=\"$mime_boundary\"\n";
        $headers .= "Content-class: urn:content-classes:calendarmessage\n";
        $headers .= "BCC: ".$BCC_to_address."\n";

        $message = "--$mime_boundary\r\n";
        $message .= "Content-Type: text/html; charset=UTF-8\n";
        $message .= "Content-Transfer-Encoding: 8bit\n\n";
        $message .= "<html>\n";
        $message .= "<body>\n";
        $message .= '<p>'.$description.'</p>';
        $message .= "</body>\n";
        $message .= "</html>\n";
        $message .= "--$mime_boundary\r\n";

        $ical = 'BEGIN:VCALENDAR' . "\r\n" .
        'PRODID:-//Microsoft Corporation//Outlook 10.0 MIMEDIR//EN' . "\r\n" .
        'VERSION:2.0' . "\r\n" .

        'BEGIN:DAYLIGHT' . "\r\n" .
        'DTSTART:16010325T020000' . "\r\n" .
        'RRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=3' . "\r\n" .

        'TZNAME:EDST' . "\r\n" .
        'END:DAYLIGHT' . "\r\n" .
        'END:VTIMEZONE' . "\r\n" .  
        'BEGIN:VEVENT' . "\r\n" .
        'ORGANIZER;CN="'.$from_name.'":MAILTO:'.$from_address. "\r\n" .
        'ATTENDEE;CN="'.$to_name.'";ROLE=REQ-PARTICIPANT;RSVP=TRUE:MAILTO:'.$to_address. "\r\n" .
        'LAST-MODIFIED:' . date("Ymd\TGis") . "\r\n" .
        'UID:'.date("Ymd\TGis", strtotime($startTime)).rand()."@".$domain."\r\n" .
        'DTSTAMP:'.date("Ymd\TGis"). "\r\n" .
        'DTSTART;TZID="Arabia Standard Time":'.date("Ymd\THis", strtotime($startTime)). "\r\n" .
        'DTEND;TZID="Arabia Standard Time":'.date("Ymd\THis", strtotime($endTime)). "\r\n" .
        'TRANSP:OPAQUE'. "\r\n" .
        'SEQUENCE:1'. "\r\n" .
        'SUMMARY:' . $course_title . "\r\n" .
        'LOCATION:' . $loc_title . "\r\n" .
        'CLASS:PUBLIC'. "\r\n" .
        'PRIORITY:5'. "\r\n" .
        'BEGIN:VALARM' . "\r\n" .
        'TRIGGER:-PT15M' . "\r\n" .
        'ACTION:DISPLAY' . "\r\n" .
        'DESCRIPTION:Reminder' . "\r\n" .
        'END:VALARM' . "\r\n" .
        'END:VEVENT'. "\r\n" .
        'END:VCALENDAR'. "\r\n";

        $message .= 'Content-Type: text/calendar;name="Training_Session.ics";method=REQUEST'."\n";
        $message .= "Content-Transfer-Encoding: 8bit\n\n";
        $message .= $ical;

        $mailsent = mail($to_address, $subject, $message, $headers);

        return ($mailsent)?(true):(false);
    }

并将其称为

$dtstart = date("m/d/Y", strtotime($session_details['start_date']));
$dtend = date("m/d/Y", strtotime($session_details['end_date']));

sendIcalEvent($from_name, $from_address, $to_name, $to_address, $BCC_to_address, $startTime, $endTime, $subject, $description, $location, $course_title, $loc_title)

我希望在iCal时区问题中遇到此问题。如何将其设置为（沙特阿拉伯利雅得）？

Answer 1

ics规范建议使用Ohlson时区db标识符（与php相同），请参见https://tools.ietf.org/html/rfc5545#page-27。看起来您需要的TZID是亚洲/利雅得。参见http://php.net/manual/en/timezones.asia.php。

请参见https://tools.ietf.org/html/rfc5545#page-35 可以以UTC时间发布日期时间，然后让应用程序转换为用户时区

DTSTART:19970714T173000Z                  ; UTC time

或带有TZID（应用程序会将其转换为应用程序中用户的时区）

DTSTART;TZID=America/New_York:19970714T133000                                        ; Local time and time zone reference.

列出的另一个选项是“本地或浮动时间”。例如，如果事件是上午8点，那么在所有时区都是上午8点。

如何在icalendar中设置计时而不增加1小时的KSA计时
