Estados afetados Horário de Verão.
São Paulo -3
Rio de Janeiro -3
Espírito Santo -3
Minas Gerais -3
Paraná -3
Santa Catarina -3
Rio Grande do Sul -3
Goiás -3
Distrito Federal -3
Mato Grosso -4
Mato Grosso do Sul -4


Como está o meu linux hoje.
# timedatectl status
Local time: Seg 2018-10-08 18:48:59 -03
Universal time: Seg 2018-10-08 21:48:59 UTC

    Realize um backup do arquivo /usr/share/zoneinfo/America/Sao_Paulo:

    # cp -v /usr/share/zoneinfo/America/Sao_Paulo /usr/share/zoneinfo/America/Sao_Paulo.bkp

    Execute o comando abaixo para gerar as novas regras para o horário de verão:

    # zic verao2018.zic

    Verifique com o comando abaixo se foram alteradas a data de início do horário de verão para 18 de novembro de 2018:

    # zdump -v /etc/localtime | grep 201[89]

    Irá aparecer conforme abaixo:

    /usr/share/zoneinfo/America/Sao_Paulo Sun Feb 18 01:59:59 2018 UTC = Sat Feb 17 23:59:59 2018 -02 isdst=1 gmtoff=-7200

    Verifique com o comando timedatectl status que foi alterada a data de início do horário de verão para 18 de novembro de 2018:

    # timedatectl status

    Sugiro fazer o teste de adiantar a data do relógio para um dia após o dia 18 de novembro para verificar se o horário irá mudar.

    Considerações importantes:

    Realize primeiramente estes procedimentos em ambiente de testes antes de implantar em produção.
    Para restaurar as configurações anteriores, simplesmente reinstale o pacote tzdata com o comando yum reinstall tzdata,
    ou simplesmente restaure o backup do arquivo /usr/share/zoneinfo/America/Sao_Paulo.

    Pelo menos com relação ao Red-Hat, é só executar " yum -y update tzdata" e o arquivo abaixo será alterado para as datas corretas. PORÉM, ainda não está disponível o patch para o dia 18. Perceba que abaixo o arquivo foi alterado corretamente para o dia 4, que era o que estava valendo até o Temer mudar para o dia 18.

    Sugiro fazer o teste de adiantar a data do relógio para um dia após o dia 18 de novembro para verificar se o horário irá mudar.

    Considerações importantes:

    Realize primeiramente estes procedimentos em ambiente de testes antes de implantar em produção.
    Para restaurar as configurações anteriores, simplesmente reinstale o pacote tzdata com o comando yum reinstall tzdata,
    ou simplesmente restaure o backup do arquivo /usr/share/zoneinfo/America/Sao_Paulo.
