导入ICS事件的时间错误 [英] Wrong Time When Importing ICS Event
问题描述
我有一个 .ics 文件，该文件具有以下iCalendar代码：
I have a .ics file that has the following iCalendar code:
BEGIN:VCALENDAR
PRODID;X-RICAL-TZSOURCE=TZINFO:-//Company Name//NONSGML example.co
m//EN
CALSCALE:GREGORIAN
VERSION:2.0
METHOD:PUBLISH
BEGIN:VTIMEZONE
TZID;X-RICAL-TZSOURCE=TZINFO:America/Los_Angeles
BEGIN:DAYLIGHT
DTSTART:20180311T020000
RDATE:20180311T020000
TZOFFSETFROM:-0800
TZOFFSETTO:-0700
TZNAME:PDT
END:DAYLIGHT
END:VTIMEZONE
BEGIN:VEVENT

SEQUENCE:0
END:VEVENT
END:VCALENDAR
但是，当我在Android设备上下载文件并导入文件时，该事件已关闭1小时。在Mac或iPhone设备上进行尝试会在正确的时间导入事件。
However, when I download the file on an Android device and import it, the event is off by 1 hour. Trying on a Mac or iPhone device will import the event with the correct time.
有人知道为什么我在Android上出现这种奇怪的行为吗？
Any idea why I'm getting this weird behaviour on Android?
推荐答案
您对美国/洛杉矶的VTIMEZONE定义是虚假的。它缺少标准组件。要查看其外观，只需邀请自己参加任何客户端的会议并查看生成的ics文件即可。
Your VTIMEZONE definition for America/Los Angeles is bogus. It is missing a STANDARD component. To see what it should look like, just invite yourself to a meeting from any client and look at the resulting ics file.
事情在Mac / iOS上是有效的，因为那些客户端倾向于忽略实际定义，而只是依靠TZID = America / Los_Angeles将其映射到自己的定义。
Things are working on Mac/iOS because those clients tend to ignore the actual definition and just rely on the TZID=America/Los_Angeles to map it to their own definition.
