How private proxies can easily be detected

I thought of a way to easily detect if someone uses a proxy.

You could have the client local timezone send to you via javascript and compare it with the timezone of his IP.

I am not sure if big sites do that but they certainly could.

One way to prevent this would be to inject javascript into the site that overwrites this ahead of all other javascript.

But then again they could check for that too...

So how can we prevent this?

How to prevent time zone mismatch? Move to the time zone of your proxies or get proxies from your time zone.
Fake your time zone?

This is not how most proxies are detected for sure. They're detected by ip ranges, sites work from a database of these known ranges. That's why residential proxies can be better than datacenter proxies.
