Welcome to Node.js v18.7.0.

> new Intl.DateTimeFormat('en-US', {timeZone: 'Europe/Kiev'}).format(data)

> new Intl.DateTimeFormat('en-US', {timeZone: 'Europe/Kyiv'}).format(data)
Uncaught RangeError: Invalid time zone specified: Europe/Kyiv

'9/6/2022, GMT-3'
# Should be GMT-4How often does it reproduce? Is there a required condition?
This is reproducible on all version of node with a dependency on icu-small.
What is the expected behavior?
See changes from tzdata 2022b in http://mm.icann.org/pipermail/tz-announce/2022-August/000071.html
Note that tzdata 2022c has also been released (http://mm.icann.org/pipermail/tz-announce/2022-August/000072.html) but contains less substantive changes.
What do you see instead?
Incorrect future timezone conversions for Chile, Ukraine, and Iran.
