Thanks, this is news to me. STP-Press is the official news agency of the national goverment, so it's reasonably authoritative. Last year, Michael Deckers found a government-sourced URL for last year's change <http://www.mnec.gov.st/index.php/publicacoes/documentos/file/90-decreto-lei-...> which said that the transition was at 01:00. I can't find anything like that this year, so we can leave the transition time out (defaulting to 00:00 local time). Proposed patch attached. Looks like we'll need another release soon, as the change takes effect in 48 hours or so.
