Not sure why you're getting downvoted. When I read the headline, my first thought was "how are they going to update the tz database on all Linuxes in the world in time?" I expect some confusion on November 1.

Here's the thread on IANA time zone mailing list where this is being discussed: https://lists.iana.org/hyperkitty/list/[email protected]/thread/66...

BC should've timed this better. They just released 2026a.

In the future, you can check if your database has been updated with this: (it should show no transition in November):

    zdump -v America/Vancouver | grep 2026
