What time period is A Series of Unfortunate Events set in?

It is in an alternate universe, set around the late 1800s and early 1900s. Snicket (Handler) says himself that this is so, but with the technology and knowledge of today. From the books, it takes part in a European English nation, with reference to North America and some other real parts of the world.

It feels very Victorian 1800s, but there are many technologies, stories, poems and other things that are mentioned that take place up to our time. (Sunny makes a reference to George W. Bush.)
