Missing time zone information when exporting asStructuredData

[jroedel]

Hey guys, great work with this package!

I'm exporting structured opening hours data to a Place and I need the information of the timezone to be encoded. I'm creating the object using the OpeningHours::create static method with a time zone passed, but it appears that the timezone is never referenced elsewhere in the code.

Could we tack on the offset according to the schema.org Time spec if there's a timezone set?

Of course we should. Good point. I will check if there is already a way to do that or if we need to add some parameter.
