This is very useful information. It may not be something you want for your current purpose, but it would be a shame to throw this information away. It's very useful to be able to identify the log lines where the timestamp recorded is significantly behind the latest timestamp seen by that point in the logs, as this identifies the long running requests, which are likely to be performance issues on your site.

Your requests.rb link is broken. Do you have a copy of this available? I’ve been looking all over fro something that does this for quite a while. Your requests.rb link is broken.
