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

Hello, we use dayjsdayjs as our time lib, and we noticed some issues related to timezone dates. At first I thought it was dayjsdayjs 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_RicoAmerica/Puerto_Rico which is the correct TZ while deno outputs America/AnchorageAmerica/Anchorage. Is this known issue?
