Since tz is now (from6eb4762fee) added to the client cookie, visitor timezone can directly be set when creating the visitor, using the request. Jstz can be removed as even for module in ENT that used this lib, we can get the timezone using Intl lib instead. This will also reduce the number of request made only to get visitor's timezone.
