0:00 - GMT 2018 Jan 1 00:00
The mentioned link quotes João Vicente Lima (director of meteorology): "A partir de janeiro de 2018, à primeira hora da manhã, vamos aumentar o relógio em mais 60 minutos" [Beginning with January 2018, at 1 hour in the morning, we are going to advance the clock by plus 60 minutes] so that the switch is from 01:00 to 02:00, not from 00:00 to 01:00. The official legislation is available at [http://www.mnec.gov.st/index.php/publicacoes/documentos/file/90-decreto-lei-...] and says the same. So we should use 0:00 - GMT 2018 Jan 1 01:00 Michael Deckers.
