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.
