Pull request overview

This pull request updates the IANA timezone database from version 2018f (released in 2018) to version 2025c (the latest release). The primary motivation is to support newly added and renamed timezones, particularly Europe/Kyiv, which is the modern canonical name for Ukraine's capital timezone (previously known as Europe/Kiev).

Changes:

  • Updated the source URL reference from tzdata2018f.tar.gz to tzdb-2025c.tar.lz to reflect IANA's current release naming and compression format
  • Added new timezone entries including america/ciudad_juarez, america/coyhaique, and europe/kyiv
  • Updated numerous timezone aliases to point to consolidated canonical zones (e.g., several European cities now map to Europe/Berlin instead of maintaining separate timezone entries with identical rules)
  • Renamed Europe/Kiev to map to the canonical Europe/Kyiv while maintaining backward compatibility
