When Azerbaijan's Ministry of Transport, Communications and High Technologies said late last month that Azerbaijan would stay at +04, its announcement mentioned the TZ database. See: [Azerbaijan will not translate time] (in Russian). Sputnik. 2017-10-29. https://news.rambler.ru/caucasus/38277699-azerbaydzhan-ne-stanet-perevodit-s... Initially I thought this was a first, but it turns out that the same ministry also mentioned tzdb (though not by name) in March 2016, here: Recommendations in connection with abolition of daylight saving time. http://www.mincom.gov.az/media-en/news-2/details/12011 (Azerbaijani and Russian translations are available.) Is the March 2016 announcement the first time a government has cited tzdb, or can readers come up with earlier examples?
