It doesn't seem like it is just iOS. I noticed an issue in my conky display this morning.

You should be able to see the bug on a *nix box with:

> date '+%m-%d-%G' # shows up as 01-01-2010

where as the following works fine.

>date '+%m-%d-%y' # 01-01-2011

I guess it's not really a bug since %G is the year of ISO week number, but it would be easy for something like this to go unnoticed until the invalid date pops up.
