I've been facing some issues with timezone with Java since yesterday (21/10/2018). Looks like java is considering that daylight saving have taken place in Brazil but it hasn't.
I created the following test to be sure
public static void main(String[] args) {
ZonedDateTime dateTime = LocalDateTime.now().atZone(ZoneId.systemDefault());
System.out.println(dateTime);
ZonedDateTime saoPaulo = dateTime.withZoneSameInstant(ZoneId.of("America/Sao_Paulo"));
ZonedDateTime cuiba = dateTime.withZoneSameInstant(ZoneId.of("America/Cuiaba"));
ZonedDateTime rightTime = dateTime.withZoneSameInstant(ZoneId.of("GMT-4"));
System.out.println(saoPaulo);
System.out.println(cuiba);
System.out.println(rightTime);
}
That gave the following output
2018-10-22T09:55:34.473-02:00[America/Sao_Paulo]
2018-10-22T09:55:34.473-02:00[America/Sao_Paulo]
2018-10-22T08:55:34.473-03:00[America/Cuiaba]
2018-10-22T07:55:34.473-04:00[GMT-04:00]
That's wrong as the current timezone to São Paulo should be -03 and America/Cuiaba should be -04
Anyone knows what's the source of the timezone information on Java? There is something I can do on my side to fix that? I know that I can fix it by setting a fixed GMT offset but I'm not fond of it.
