Not working

Set IP to Russia and timezone to Russian and it still allows me in. https://imgur.com/a/811EA5u

I found one reproducible timezone bug that can cause Russian traffic to skip the IP check: the script listed Asia/Ust, but the valid IANA timezone is Asia/Ust-Nera.

Opened #17 with the fix and a regression test. I used Refs #9 rather than an auto-close keyword because the original report did not include the exact timezone/browser setup.
