AW: Brazil rule issue

[Gerber, Oliver]

Hi Alain,
 
the rule
 
Rule    Brazil  2008    max     -       Oct     Sun>=15 0:00    1:00    S

gives a rule for October, i.e. the change from standard time to daylight saving time (as Brazil is on the Southern hemisphere).
 
All other rules give dates in February, i.e. the changes from daylight saving time to standard time. These rules are affected by the carnival dates.
 
So the rule mentioned above is not conflicting with the other rules.
 
I hope, I hould help you.
 
Best regards,
Oliver

Betreff: Brazil rule issue


Hi
 
I am looking in the Brazil rules and I was wondering if this was expected:
 
<snapshot>
 
Rule    Brazil  2007    only    -       Oct     Sun>=8   0:00   1:00    S

# Acording to this decree
# <a href="http://www.planalto.gov.br/ccivil_03/_Ato2007-2010/2008/Decreto/D6558.htm">

Rule    Brazil  2038    max     -       Feb     Sun>=15 0:00    0       -

</snapshot>
 
 
There is 2 'max' entry for Brazil, one for 2008, and one for 2038.
Rule    Brazil  2008    max     -       Oct     Sun>=15 0:00    1:00    S
Rule    Brazil  2038    max     -       Feb     Sun>=15 0:00    0       -

Reading the entries for 2012+ I feel that the one for 2008 should be a 'only' rather than 'max'.
 
Is that correct?
 
Thanks
Alain Petit
