Why are downloaded .ics events only in UTC?

Why are downloaded .ics events only in UTC?

When I schedule a meeting for the future, and click the "add to calendar", that event is downloaded as an ,ics file.   That event is shown as an offset to UTC when adding to Google.  The time is technically correct if you save the event, but the time shown is 8 hours off for my attendees if they only look at the time itself.

Not everyone looks at the time zone when replying to events, and it confuses people to have to count back from UTC.  Why not save the .ICS file with the correct time zone embedded?  I have saved my timezone in my preferences in Zoho Meeting, so why not adapt the .ics file to my timezome?
