Alberta Time Zone change

Alberta, Canada is getting a new time zone, UTC -06:00. Takes effect November 1, 2026. Do we have to update the Time Zone for our 1Password environment? What are the steps to do so? We had an experience with a different 3rd party app which uses time zones, and are setting up to use with SSO. When I changed it to the new Time Zone, our users began having issues signing in. I reverted the Time Zone back for that environment, and people were once again able to sign in.
