Will this break around DST transitions that PDT is unaware of? That may be OK for a cookbook sample, but it may deserve a comment.
There was a problem hiding this comment.
I don't think it'll break. this.#impl.toPlainDateTime() will be unaware of any DST transitions at all, but adding this.offsetNanoseconds will correctly account for DST transitions in the VTIMEZONE.

This is an example of how a ZonedDateTime object with a custom time zone could work, if TimeZone objects are removed. (#2853)
This shows integration with ical.js. It's a ZonedDateTime-wrapper object that internally maintains a real
Temporal.ZonedDateTimeobject, but it takes anICAL.Timezoneinstead of aTemporal.TimeZone. If theICAL.Timezoneobject has the ID of an IANA time zone, we delegate everything to the realTemporal.ZonedDateTimeand use the host's time zone database. If the ID is not an IANA ID, we fall back to theICAL.Timezone'sVTIMEZONEdata.Draft; still needs test data with which to make sure everything works, and a cookbook page.
