In Discourse we call the Rails Timezone class, which is a wrapper of the TZInfo gem, which reads from the tzdata of the underlying OS. We use Debian for our container image and I believe it sources it from [Time Zone Database](https://www.iana.org/time-zones). So it may be better taken to IANA, in order to fix it everywhere.
