That's not going to work on a website with restrictions like this. The restriction is set on the web server, not on the client. Limiting client access by what time it is where THEY are is not a thing.

On one hand, this seems unlikely to work because it's easier to check the server's clock for the time. On the other, it'd be a mistake to expect the government to take the straightforward option when there's a perfectly good ass-backwards way to screw it up.
