Spacetime not working in MacOS Sonoma (Cannot find timezone named: 'cet'. Please enter an IANA timezone id) about spacetime HOT 7 CLOSED

thank you. Yup - I will release a hotfix this afternoon.
appreciate the help.

from spacetime.

I will open a bug to Apple as feedback for Sonoma; at least we'll know if it's something planned or needs fixing on their side.

We may help you with the implementation if you consider that it should be fixed ;) Maybe you should allow the same approach that you use at timezones-soft in the lookupTz function or add cet and cest as aliases, but we should explore if it happens elsewhere.

oh my gosh - thank you for the heads-up.
Is this documented anywhere? Yeah, I'm happy to fix this asap.
Yep, at minimum we can add a guard to prevent the runtime error.
Please let me know if you can dig anything up about this change. I can't believe they're returning non-IANAs.
oof!
thank you.

Since the heads up from one of our customers, we have been trying to reproduce it, and we were able to reproduce it with the last beta updating one of our laptops. At least here where we were getting 'Europe/Madrid', we are getting 'cet'; configuring the timezone manually to 'Europe/Madrid' does not change it back to 'Europe/Madrid' and keeps returning 'cet.'.

We did not find any documentation regarding it... But we are kind of lost on where Apple tracks these types of changes.

Since you have the aliases, maybe we can extend them to include cet, met, eet and wet and use them to check if the returned value of Intl.DateTimeFormat().resolvedOptions().timeZone is an alias and return the IANA value of them.

ok - released a fix for this as 7.4.7 - but would love some help testing it against any variants of this.

Yeah - turns-out there's even-weirder responses than 'CET' from the Intl api, apparently you can get the result 'Factory'. No idea how, but it appears in:

Intl.supportedValuesOf('timeZone')

I added a test for the Node 18, and Firefox results, but I'm sure there's more to be found. I aliased them to whatever it said in wikipedia. - but please let me know if I've done something foolish. There's always a good chance of this.
cheers

I'll take a look at both the supported values that I get on Chrome and the values that we get on Sonoma.
