Alex,

What spec are you referring to?  Link?  I was playing around with NSDataDetector for pulling dates out of strings in XML dumps of excel files for an internal tool I was writing.  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?

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.
