Subject: [PATCH 1/2] settings: Catch runtime_error, fallback time zone

Windows will let you select time zones that  will fail in their
own C++ implementation library. Evidently from the stack trace, we get a
runtime error to work with, so catch it and use the fallback.

Subject: [PATCH 2/2] settings: Clean up includes

Adds <version> since we are looking at C++ implementation version
details. Also moves exception header includes into the if preprocessor
command since we only use it there.
