Hello Luke,

 Seems to be a missing function in Mono.

Unlikely, if the Wine version you specified is correct.
The support for using 'GetTimeZoneInformation' was added with Wine-Mono 4.5.6

Wine-Mono supergit:

https://github.com/madewokherd/wine-mono/tree/wine-mono-4.5.6

Submodule:

https://github.com/mono/mono/commit/8a91a10

Use GetTimeZoneInformation to find the current timezone.

For wine bug 37760.

diff --git a/mcs/class/System.Core/System/TimeZoneInfo.cs

--- snip ---
[DllImport ("kernel32.dll", CallingConvention=CallingConvention.StdCall)]
private extern static uint GetTimeZoneInformation(out TIME_ZONE_INFORMATION
tzi);
...

Works fine here:

--- snip ---
$ WINE_MONO_TRACE=wrapper MONO_LOG_LEVEL=debug wine ./Coop-Launcher.exe | grep
GetTimeZoneInformation
...
Mono: Searching for 'GetTimeZoneInformation'.
Mono: Probing 'GetTimeZoneInformation'.

--- snip ---

It's very likely that you're using native Linux Mono runtime and not Wine-Mono
here, making the bug report invalid.
