C++ Retrieve client's TimeZone at runtime

Does Unreal 4 provide means of retrieving a client’s TimeZone via C++?

My goal is to provide the game server with FDateTime.Now() with an appended ±0800 or “Australia/Aus”.

I’m hoping for an Unreal api instead of having to calculate UtcNow() - Now(), because I would then need to find IsDst() and adjust accordingly.
