So for better timezone consistency, I would suggest to that we simply drop this change to rigidly fix is_dst, and use what is in 2023c. This follows the intention of the timezone change
As I understand things, Greenland Prime Minister Múte Bourup Egede said "Greenland will not switch to Daylight Saving Time this year", so the intent was that tm_isdst should be zero all year. As you say, real software by and large doesn't care about tm_isdst any more. This is why we haven't bothered to issue a new TZDB release yet - nobody cares in the real world. But eventually when the next TZDB release comes out I'd like the tm_isdst flag to reflect better the intended rules by Greenland's government, as we might as well do things right if it's easy. I expect will care about this except us TZDB nerds. The NEWS file does need a fix now, though; proposed patch attached.
