Hello,

How is it possible to get the timezone for a specific datetime and a (ISO3166-1 alpha2, ISO3166-2) pair, i.e. a country code + region code ? 

Example: 
ISO3166 -> Timezone
DE-BE -> Europe/Berlin
AU-TAS -> Australia/Hobart or Australia/Tasmania
US-NY -> America/NewYork

Thank you in advance,
Jo

PS: I have seen the file "iso3166.tab" but this is only for country codes, i.e. the first part of ISO3166.
