in thread Weird date format behavior with WWW::Mechanize

See, now that you've given a concrete example to look at you can easily see that the page in question (after you accept their disclaimer thing and get back a session cookie . . .) has the full date text. The page contains a call to pull in a JavaScript file "common.js". Said "common.js" contains a function formatDate which looks to munge dates.

Given this it's not out of the realm of possibility that there's something calling javascript and munging all the dates. This easily explains the difference between what you see in your browser (even if you view source, you're seeing the source after it's been walked over) and what Mechanize is showing. You can easily confirm this by comparing the output from a third party (say curl and using the JSESSIONID cookie value pulled from your browser) which should match what Mechanize says it is.

    Thanks, I'm impressed. I had never noticed you can look inside the js source code before. I'm still confused about how Mechanize would be getting the munged date but a normal browser wouldn't, but regardless, the solution lies in the formatting.

      Because a browser can run JavaScript, and WWW::Mechanize can't (update: though other modules can, e.g. JavaScript::SpiderMonkey - as suggested by Fletch). Anyway, it's the (JavaScript in the) browser that is munging the date, not WWW::Mech.
