Vou deixar aqui uma dica para aqueles que não poderão trocar o horário do servidor (linux) no momento da virada do horário de verão 2006.

1. Crie o script horario_verao_2006.sh

[code]
vi /root/horario_verao_2006.sh
[/code]

2. Copie e cole o conteúdo abaixo

[code]
#!/bin/sh

date -s "2006-11-05 01:00"

# Pacotes que devem ser reiniciados
/etc/init.d/mysql restart
/etc/init.d/postgresql restart
[/code]
Obs: Inclua ou retire os pacotes que devem ser reiniciados de acordo com os serviços que rodam no seu servidor.

3. Mude a permissão do arquivo para torná-lo executável

[code]
chmod u=rwx,g=rx,o= /root/horario_verao_2006.sh
[/code]

4. Copie e cole a linha abaixo no arquivo do cron

[code]
0 0 5 11 * /root/horario_verao_2006.sh
[/code]

5. Reinicie o cron

Agora você pode viajar sossegado e aproveitar o feriado!

To localize the distance_of_time_in_words and time_ago_in_words methods of Ruby on Rails with Globalize Plugin, put these lines on your app/helpers/application_helper.rb

[ruby]
def distance_of_time_in_words(from_time, to_time = 0, include_seconds = false)
from_time = from_time.to_time if from_time.respond_to?(:to_time)
to_time = to_time.to_time if to_time.respond_to?(:to_time)
distance_in_minutes = (((to_time – from_time).abs)/60).round
distance_in_seconds = ((to_time – from_time).abs).round

case distance_in_minutes
when 0..1
return (distance_in_minutes==0) ? ‘less than a minute’ : ‘1 minute’ unless include_seconds

case distance_in_seconds
when 0..5 then “less than %d seconds”.t / 5
when 6..10 then “less than %d seconds”.t / 10
when 11..20 then “less than %d seconds”.t / 20
when 21..40 then “half a minute”.t
when 41..59 then “less than a minute”.t
else “1 minute”.t
end

when 2..45 then “%d minutes”.t / distance_in_minutes
when 46..90 then “about 1 hour”.t
when 90..1440 then “about %d hours”.t / (distance_in_minutes.to_f / 60.0).round
when 1441..2880 then “1 day”.t
else “%d days”.t / (distance_in_minutes / 1440).round
end
end[/ruby]
