Php ICS URL输出延迟5小时

首先，我要说我不是PHP开发人员。因此，我让另一位开发人员创建了一个插件，它从Wordpress插件CalendarizeIt获取开始和结束时间，并将其输出到格式化的ICS url中。问题是url输出的开始和结束时间比它应该的时间早了5个小时

以下是PHP的插件：

<?php
// Original script from http://jamiebicknell.tumblr.com/post/413492676/ics-generator-php-class#_=_
// Modified by Sean Carruthers

$start          = $_GET['start'];
$end            = $_GET['end'];
$name           = $_GET['name'];
$description    = $_GET['description'];
$location       = $_GET['location'];
$uid            = "kaneko" . strtotime("now");

$data = "BEGIN:VCALENDAR\r\nVERSION:2.0\r\nMETHOD:PUBLISH\r\nBEGIN:VEVENT\r\nDTSTART:".date("Ymd\THis\Z",$start)."\r\nDTEND:".date("Ymd\THis\Z",$end)."\r\nLOCATION:".$location."\r\nTRANSP: OPAQUE\r\nSEQUENCE:0\r\nUID:".$uid."\r\nDTSTAMP:".date("Ymd\THis\Z")."\r\nSUMMARY:".$name."\r\nDESCRIPTION:".$description."\r\nPRIORITY:1\r\nCLASS:PUBLIC\r\nEND:VEVENT\r\nEND:VCALENDAR";

header("Content-type:text/calendar; charset=utf-8");
header('Content-Disposition: inline; filename="'.$name.'.ics"');
echo $data;
?>

我尝试将插件的

$uid

变量中的strotime更改为

+5小时

，但似乎不起作用

任何帮助都将不胜感激

哦，我还在Wordpress设置中修改时区。当前设置为UTC-5，因此我认为将其改为芝加哥会有所帮助，但也没有。在下面的行中添加

X-WR-TIMEZONE:America/NewYork

$data=“BEGIN:VCALENDAR\r\n版本：2.0\r\n方法：发布\r\nX WR时区：美国/纽约\r\n

更新：我已经更新了整行代码，它使用

DTSTART；VALUE=DATE:

而不使用

Z

和

DTEND

$data = "BEGIN:VCALENDAR\r\nVERSION:2.0\r\nMETHOD:PUBLISH\r\nX-WR-TIMEZONE:America/New_York\r\nBEGIN:VEVENT\r\nDTSTART;VALUE=DATE:".date("Ymd\THis",$start)."\r\nDTEND;VALUE=DATE:".date("Ymd\THis",$end)."\r\nLOCATION:".$location."\r\nTRANSP: OPAQUE\r\nSEQUENCE:0\r\nUID:".$uid."\r\nDTSTAMP:".date("Ymd\THis\Z")."\r\nSUMMARY:".$name."\r\nDESCRIPTION:".$description."\r\nPRIORITY:1\r\nCLASS:PUBLIC\r\nEND:VEVENT\r\nEND:VCALENDAR";

感谢您的快速回答。不过，这似乎不起作用。您能为我们提供提要的输出吗？当然可以：

http://thekaneko.org/wp-content/plugins/kaneko/calendarize-it-mods/ics_event.php?start=1376388000&end=1376409600&name=The%20Millennial%20Trains%20Project&description=&location=KANEKO%20|%201111%20Jones%20St&

I更新了上面的答案，试试我给你的新台词

<a href="<?php echo $ics_url; ?>">

$data = "BEGIN:VCALENDAR\r\nVERSION:2.0\r\nMETHOD:PUBLISH\r\nX-WR-TIMEZONE:America/New_York\r\nBEGIN:VEVENT\r\nDTSTART;VALUE=DATE:".date("Ymd\THis",$start)."\r\nDTEND;VALUE=DATE:".date("Ymd\THis",$end)."\r\nLOCATION:".$location."\r\nTRANSP: OPAQUE\r\nSEQUENCE:0\r\nUID:".$uid."\r\nDTSTAMP:".date("Ymd\THis\Z")."\r\nSUMMARY:".$name."\r\nDESCRIPTION:".$description."\r\nPRIORITY:1\r\nCLASS:PUBLIC\r\nEND:VEVENT\r\nEND:VCALENDAR";
