[tz] Did Greenland abolish daylight saving from 2024 on?

[Paul Eggert]

This week several English-language news sources reported that Greenland 
has moved its clocks forward for the last time. These reports disagree 
with current TZDB[1], which follows Thomas M. Steenholdt's December 
email[2] saying that although in November Greenlanders voted to not fall 
back this fall, they also voted to continue to observe daylight saving 
time (DST) next year, effectively moving their time zone one hour east 
instead of abolishing DST.

There's no disagreement about timekeeping this year. The first point of 
disagreement is March 30, 2024 at 23:00, when TZDB says Nuuk, Greenland 
will spring forward to 24:00, whereas the recent news reports say clocks 
will neither spring forward nor fall back during 2024.

So who's right: Steenholdt in December, or these several recent news 
reports? Currently TZDB goes with Steenholdt. After all, he cited the 
relevant Greenland legislation and his email address ends in ".gl". I 
suppose another possibility, though, is that Greenland's government has 
changed its mind since November. However, if so I'd like to see 
citations to the newer legislation.

The earliest recent news story I found on this topic was a week ago by 
Lebawit Lily Girma[3], senior travel news reporter for Bloomberg 
Pursuits. I'm taking the liberty of bcc'ing Girma to see if she can help 
get to the bottom of the situation.
