Someone helped me with some testing in their Win7 x64:

# Their timezone
$ tzinfo => Timezone is "C" (daylight).
$ date => Sat Oct 20 22:31:31 CDT 2012

# Brasília (UTC-03:00)
$ tzinfo => Timezone is "E" (daylight).
$ date => Sun Oct 21 01:31:54 ESADT 2012

Thanks to the help of another guy, I figured out I actually want "%ls" in printf, so new code is .

* so new code is http://pastie.org/5091808.
Output is now:

# Their timezone
$ tzinfo => Timezone is "Central Daylight Time" (daylight).

$ date => Sat Oct 20 22:31:31 CDT 2012

# Brasília (UTC-03:00) to them
Timezone is "E. South America Daylight Time" (daylight).

$ date => Sun Oct 21 01:31:54 ESADT 2012

# Brasília (UTC-03:00) to me
Timezone is "Horário brasileiro de verão" (daylight).
$ date => Sun Oct 21 05:08:25 GMT 2012

They also helped me find out some MSYS code which may be relevant, maybe MSYS just tries to make an acronym out of timezone name (the ESADT above having been come from "E. South America Daylight Time"), like it seems from [1]? And maybe I get GMT in date when TZ in unset due to likes 702-705 in [2]? If this is correct, the root cause of the whole problem seems to be that my timezone name is localized and for some reason MSYS can't handle that.

Sorry for the quite big amount of consecutive messages.

MSYS uses the GetTimeZoneInformation windows API.  Create a program to
determine what it returns.  You might create another to

Ok, so here is my program: http://pastie.org/5089934. Surprisingly, in Windows 7 it says my timezone is "H".

I have found timezones registry key and mine is not missing: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\E. South America Standard Time, and it looks alright. So I have no idea what's happening here.

How about your machines, what does this program say for your timezones, and if you temporarily switch to Brasília (UTC-03:00) from control panel?
