Hello, don't know what is geoip at all :). (detect placement by IP?). Some services by IP address return pair {"US"(or something), <some 2 symbol tag>}. Is it corrent? How did you get you list? Is it possible to get this information automatically?

Hi!

don't know what is geoip at all :). (detect placement by IP?).

yes

Some services by IP address return pair {"US"(or something), }. Is it corrent?

yes, It is by REST API or lookup from local database for example http://www.maxmind.com/en/geolocation_landing http://ru.smart-ip.net/geoip-api http://geoip.pidgets.com/ http://freegeoip.net/static/index.html http://wiki.nginx.org/HttpGeoipModule

How did you get you list? Is it possible to get this information automatically?

you can get country code by ip via many geoip services. Most popular is maxmind

my suggestion is using database from maxmind (or your own database) http://dev.maxmind.com/static/csv/codes/time_zone.csv to resolve timezone by country code from geoip service
