Could you clarify which specific time zone you're seeing an issue with, which version of TZDB you're using, and what tool you're using?

For example, from https://nodatime.org/tzvalidate/generate?version=2023c, both "Mexico/General" and "America/Mexico_City" are in CST (from October 2022 onwards). "Mexico/BajaNorte" is still alternating between PST and PDT. "Mexico/BajaSur" is now in MST (from October 2022 onwards).

Hello,

Mexico has recently abolished daylight savings except for where they border with the United States. I believe the timezone database is now inaccurate because it should not be showing CDT for most of the country any longer and should be CST instead. It seems like this was addressed in release notes for the tzdb version 2022f and 2022g but I'm not sure that the correct changes were applied. Could you verify/explain why the timezones in Mexico are still recorded as CDT? Is this a mistake?

Thank you
