How should Intl.DTF `timeZoneName` option be formatted in this proposal? #8

One interesting question would be how the timeZoneName option should be handled. It seems reasonable to use the IXDTF format (the one we're working with IETF to specify) like 2020-12-25T12:34:56[America/Los_Angeles].

This formatting can also be delegated to Temporal AOs if needed.

It also makes sense to specify in this proposal whether the options bag {timeZoneName: "long"} should assume a full date should be shown like 2020-01-01[America/Los_Angeles], or if only America/Los_Angeles should be returned. I assume the former for backwards compatibility?

Using the IXDTF format does sound sensible.

It also makes sense to specify in this proposal whether the options bag {timeZoneName: "long"} should assume a full date should be shown like 2020-01-01[America/Los_Angeles], or if only America/Los_Angeles should be returned. I assume the former for backwards compatibility?

I don't think that's necessarily within scope; the behaviour should match what's used with other locales.
