System.InvalidTimeZoneException: Exception of type
'System.InvalidTimeZoneException' was thrown.

I know this timezone message is mostly harmless, but the .NET program I was
trying to run refused to open because it wasn't able to find my timezone. I
also 
 get a bunch of these timezone message on any program I try to run with Wine
and it's kinda annoying. Here's my timezone information:

$ timedatectl status
               Local time: qui 2018-09-06 15:16:47 -03
           Universal time: qui 2018-09-06 18:16:47 UTC
                 RTC time: qui 2018-09-06 18:16:47
                Time zone: America/Sao_Paulo (-03, -0300)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

This tool I'm trying to run is called GTA: San Andreas Downgrader, here is the
hash:

$ sha1sum sadowngrade1-3-1.exe 
c8a07ec161e2d4959c86949cc0961475590aee31  sadowngrade1-3-1.exe

Unfortunately, the tool itself doesn't work properly even if I set a "valid"
timezone, but my point is that it won't even _run_ with my default timezone.
