I think adding the iana attribute here was what we agreed in the meeting today?

We didn't have time to finish discussing this point but I have some concerns with using iana="Factory". Since ECMAScript already returns "Etc/Unknown", I think it would be a potential web compat concern if we started returning "Factory". It might be better to just change ECMA-402 to allow "Etc/Unknown" as a return value.

If I remember correctly from the last time I investigated this, different engines handle the Etc/Unknown value returned from ICU differently. And when we discussed the prospect of adding Etc/Unknown to ECMA-402 at a TG2 meeting (I think it was June 2023), if I remember correctly Yusuke did not support adding it. Also, Anba expressed the same anti-Etc/Unknown opinion here: tc39/ecma402#825 (comment).
I'm just looking for any cross-engine consensus for what ID to return when ICU returns Etc/Unknown. I don't have a strong opinion either way. If we can convince the other implementers that Etc/Unknown is OK, then I'd support that.

This PR was just created for reviewing one of possible solutions. @justingrant and I could convince TZ database folks to make these legacy IDs as aliases. So this PR is no longer needed. #3754 created by @justingrant is reflecting coming TZ database changes (2024b). |
