> I've noticed that if you use 'YYYY' instead of 'yyyy', the year is parsed as one less than the specified year, and the other values are not parsed correctly.
> Response from Steve:
> Regarding the odd output of YYYY: I'm not exactly sure why this doesn't work, but I'm not surprised. From what I can tell, YYYY is the year part of the ISO Week Date. This uses a modified gregorian calendar, so I'm not surprised you're getting odd results. However, I've tried creating a pattern that uses the ISO Week Date formatting symbols ("YYYY-'W'ww-e") and try to parse the examples from the wiki page. I get dates similar to the examples, but they are usually off by a few days. So I'm not sure what's wrong. I don't think this is a blocker for Spin 7, so please create a new bug for the YYYY issue, and we'll fix it as we find time.
