src/timezone/README mentions

  When there has been a new release of Windows (probably including Service
  Packs), the list of matching timezones need to be updated. Run the
  script in src/tools/win32tzlist.pl on a Windows machine running this new
  release and apply any new timezones that it detects. Never remove any
  mappings in case they are removed in Windows, since we still need to
  match properly on the old version.

It's been some years since this was last done (a79a68562, looks like).
Anybody want to check if updates are needed?
