Pass timezone to parse(), stringify() and item() #3
Description
It might be nice to add a way for parse(), stringify() and item() to take a separate timezone argument, so if you're doing development where the user's timezone isn't the same as the system timezone (say, for a Web application), you can pass the user's timezone in.
Maybe a second argument to each of these methods, like an options object? That way if we have other parse/stringify options in the future, they can be added without a problem.
