Bug on Date and time preference (Brazilian time!)

Hi,

Sorry for any mistake, but this BUG was big! So I will write down in portuguese too!
Today 12/10/2008 I found a BUG on "Date and time" preference. O have Mac OS 10.5.5, intel Imac.
My "time zone" is Brasilia - Brazil. The bug occurred on the night of 11/10/2008 to 12/10/2008, when it get 00:00 the clock was show 1 hour more. I have automatically update and thing the the summer time was set by the server, so when I turn off the automatically set and tried to manual change, it's get 2 hours less. example: on midnight 11/10 to 12/10 my clock chanded to 1 am! Than when I put 00:01 it show 23:01 and date change to 11/10 again!

This happen on São Paulo Time.. .but not in Recife!

Portuguese

Eram 23:30 do dia 11/10 quando fui jogar um pouco, quando parei já eram 1:20 da manhã do dia 12/10! Quando conferi o horário eram 00:20 ou seja o relógio do Mac tinha ficado doido!!
Foi nas preferências e como o "set date & time automatically" estava ligado eu pensei que alguém já tinha ajustado o horário de verão. Desliguei e manualmente tentei colocar para as 00:20. Ao invés de sair das 1:20 e ir para 00:20 do dia 12/10 ele foi para as 23:20 do dia 11/10!

Ou seja o relógio aqui tá doido! Ele volta a hora e o dia também!

O meu "time zone" está em Brasília, tentei colocar em São Paulo, mas deu o mesmo problema. Tentei mudar o servidor da Apple e todos atualizam com 1 horas a mais! Notei que se coloco Recife ele **** 00:20, e ajusta normalmente! Tanto para frente quando para trás nas horas. Mas em São Paulo e Brasília ele dá o bug! (e isso como a atualização automática desligada, se ligo ele com Recife ele **** a hora certa 00:20)

O problema parece estar na virada do dia 11/10 para o dia 12/10! Estando dia 12/10 1:20 am eu tento mudar ele muda para 23:20 do dia 11/10. Alguém tenta verificar se ocorre no seu computador também? Alguém notou a hora errada?

Estou com 10.5.5

Imac Intel 2.0ghz 1MB ram, Mac OS X (10.5.5)

Same problem here. Apparently Apple's main time server (time.apple.com) thinks Brazil already entered our Daylight Saving Time (DST) period, though it is actually scheduled to start in one week from now. The fact that the problem is solved by setting the geographical area to "Brazil / Recife" is further evidence that it must be the case, since Recife is one of our states that don't observe the DST.

I have the exact same problem.
Already tried to update the timezones with the 'zic' command on the terminal but it only works for the terminal date and not for the graphical interface.

Yes, but the point is:

If you are using the automatically update for date and time, this problem could happen by guest that the server send a wrong information. Since DST is scheduled by each country but not change every year as Brasil do, the server was programed to change. OK, If you could set manually, but you don't!
Since the problem still happening on "manually" setting this is a Apple BUG!

I have updated the zoneinfo database with the brazilian dst changes for 2008, also I have followed some hits from a BSD forum and the time is still wrong.

Seems that the system is reading the dst info from a directory different from /usr/share/zoneinfo.

I don't know if its a bug of the system, but til Apple tell us how to fix it I will set my timezone to Recife instead Rio de Janeiro. This solved the different times from terminal and graphical interface.

It isn't the server that determines the local time but the settings & data files in the OS that derive local time from Coordinated Universal Time (UTC) supplied by the server. When local governments change the rules for the date of the DST switch, the data file(s) containing the rule information must be updated on each computer in way that each OS understands. Unfortunately, for OS X this seems to be more complex than recompiling files in /usr/share/zoneinfo with the "zic" command, so users apparently cannot do this for themselves.

Your best bet is to send Apple feedback about this, asking for an update containing the appropriate files.
