Deno vs Node `Intl.DateTimeFormat().resolvedOptions()` discrepancies

Hello, we use

dayjs

dayjs

as our time lib, and we noticed some issues related to timezone dates. At first I thought it was

dayjs

dayjs

plugins misbehaving or giving problems, but then I used

Intl.DateTimeFormat().resolvedOptions()

Intl.DateTimeFormat().resolvedOptions()

to verify the detected system TZ and notices a huge discrepancy.

Node is outputting

America/Puerto_Rico

America/Puerto_Rico

which is the correct TZ while deno outputs

America/Anchorage

America/Anchorage

. Is this known issue?
