How to set the time zone of an event?

[raxod502]

When I put my events into Apple Calendar, they show up as "Time zone: Floating". This makes sense since I didn't provide any time zone to ics.js when I created the events. That leaves the question: how do I provide the time zone?

This can be done with Date objects (and Date-friendly formatted strings) as described here.
For example, I am writing this at 2018-09-24T22:33:13-07:00

• 2018-09-24 is the date
• 22:33:13 is the time
• -07:00 is the offset of my time zone relative to UTC time

Maybe I'm missing something, but that doesn't seem to fix the problem. All adding a time zone does is shift the time. It doesn't actually add a time zone, so I would still expect them to show up as "Time zone: Floating".

No, I think I might have misunderstood your question. The above can be used to specify a local time in some time zone (i.e. with some offset), which can then be interpreted as "absolute time" when you import the events. I believe Google Calendar, for example, translates events to whatever local time zone you import from (or has an option to do so). On closer inspection, you are probably looking for specifying the time zone for the calendar app using VTIMEZONE, which unfortunately seems to be unimplemented right now :-(

Yes, I think you're right. Meanwhile there are alternative projects such as ical-generator which are probably better choices than ics.js for a number of reasons. I'm probably going to be switching.
