I'm using Maxmind's GeoIP2 products to extract timezone IDs and then using JodaTime to parse/manipulate those timezones. I've noticed that there are timezones that are returned form GeoIP2 that are not in JodaTime's available list of timezones, such as "Europe/Kirov"

I'd like to properly parse all timezones, but without insight into what timezone database/directory Maxmind is using, I don't know how to begin. Does anyone know what they're using?

MaxMind pulls the geographical data in GeoIP2 from GeoNames, which uses the IANA Time Zone Database. See this file for Europe/Kirov. This entry was added in the 2016d release of the IANA database. JodaTime 2.9.4 should include it.
