Horário de verão

Fonte: http://tudoecompanhia.blogspot.com/2008/10/ajustar-horrio-de-vero-no-linux.html

Ajustar horário de verão no linux

- Primeiro veja se existe no diretório /usr/share/zoneinfo/Brazil algum arquivo que contenha informações relativas a horário de verão (geralmente é um arquivo com extensão .zic).

- Se existir, copie o antigo e renomeie a cópia para 'verao.2008.zic', por exemplo. Se não existir, crie um novo, com o mesmo nome, no diretório citado acima. Este arquivo deve conter as seguintes linhas:

Rule Brazil 2008 only - Oct 19 00:00 1 S

Rule Brazil 2009 only - Feb 15 00:00 0 -

Zone Brazil/East -3:00 Brazil BR%sT

(Essas são as datas corretas para o horário de verão deste ano aqui no Brasil)

- Após isso, execute o comando 'zic':

# zic verao.2008.zic

- Para finalizar, deve-se copiar o arquivo East (que está na pasta /usr/share/zoneinfo/Brazil) para /etc/localtime

# cp East /etc/localtime

- Agora é só executar o comando:

# date

e o horário já deverá estar corrigido.

Script para linux

#!/bin/bash

rm -rf /etc/localtime
