NSDataDetectors seemed powerful, but failed when the dates weren't totally well formed (Tested on 10.8.5, SDK 10.8); the dates were still totally recognizable by humans, just missing some whitespace here or there. It did handle differently formatted dates very well though. I ended up using regular expressions to 'parse' the dates as there was just one format I was dealing with and the issue was just the missing whitespace. Maybe I didn't know how to configure it to be more flexible or tolerant of the format deviations?
Fortunately, Twitter seems to do things consistently. I'll reg-exa it if I discover problems in testing, but it works for now. Using setDateFormat("[standard symbols]") did the job.

>>> Thanks for the suggestion. I don't think that would apply here, though; I have some JSON data that includes a date as a string. I need to convert that to an NSDate object so I can then display it however the user wants, or compare it to now, and such. However, that's a really useful page (I love NSHipster) and I'll save it for another project I'm thinking about where data detectors will be useful.
