+1 This fixed my issues with cucumber-selenium tests failing with cryptic "can't convert nil into an exact number (TypeError)" when calling `#visit` method for browser.

Another solution is `cattr_accessor` but that means the subclasses have access to'timing_offset`, which might not be desirable (but they shouldn't know or care about it).
