Ao executar a verificação de pré-requisitos para adicionar um nó no Clusterware, recebi o seguinte erro:
Verifying Time zone consistency ...FAILED
PRVF-5479 : Time zone is not the same on all cluster nodes.
Found time zone "EST5EDT" on nodes "rac03".
Found time zone "-033-02" on nodes "rac01".
O timezone do nó que seria adicionado (rac03) era diferente do timezone do nó em que estava executando a verificação (rac01).
