Improve error message when time.LoadLocation fails

[BinaryFissionGames]

time.LoadLocation may fail due to a missing time zone database. This is especially relevant on Windows, since there aren't any "default" locations checked.

When this error occurs, the error returned is simply: The system cannot find the path specified. This error should be wrapped to include that this was a failure to load location information, and that the time zone database may not be installed.
