As a developer,

I would like to have a built in timeout exception,

So that I can do logic related to this specific exception.

Imagine a scenario where I am implementing a circuit breaker pattern so that I can stop calling an external service if it times out X amount of times. 

In the server context, to know if the service has timed out, we need to have an "All Exception" handler and check for the message

"The operation has timed out"

Checking for an hardcoded string is obviously not great, and could be easily solved by adding a built in exception
