Bug ID: 49119
           Summary: Timezone America/Sao_Paulo reconigzed as
                    America/Buenos_Aires
           Product: Wine
           Version: 5.7
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: loader
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Timezone is not recognized and probably changed:

http://mm.icann.org/pipermail/tz-announce/2019-July/000056.html

Running from archlinux or ubuntu has the same results.

```
$ wine --version
wine-5.7
```

```
$ printenv      
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOSTNAME=ea9649867742
TERM=xterm
HOME=/home
DEBIAN_FRONTEND=noninteractive
LC_ALL=pt_BR.UTF-8
LANG=pt_BR.UTF-8
LANGUAGE=pt_BR.UTF-8
TZ=America/Sao_Paulo
WINEPREFIX=/root/prefix32
WINEARCH=win32
DISPLAY=:0
```

```
$ cat /etc/timezone 
America/Sao_Paulo
```

**Finally**, when checking wine windows registry it is recognized as another
Zone (creating troubles with a proprietary .NET software I use):

```
$ wine reg query
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation"    
002c:fixme:ntdll:NtQuerySystemInformation info_class
SYSTEM_PERFORMANCE_INFORMATION

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation
    StandardName    REG_SZ    Hora padrão da Argentina
    TimeZoneKeyName    REG_SZ    Argentina Standard Time
```

Bug appears to be similar to other related timezone changes.

Question: How can I tell that my local timezone is the same as specified in the
`loader/wine.inf`?
