It seems that the IRLDB does not support 2010. I know what it feels like, it doesn't really feel like 2010 to me either. ;-)
Yeah, so if you do a IRLDB search with one of the "yyyy/mm/dd" date display options used then dates in 2010 will be displayed as 1000/00/00 (I presume that means 'no date' or 'invalid date').
See Lost Labryinth for example.
On a related note I'm considering altering the templates used in Roguebasin so that the Released and Updated lines are formed from _two_ fields each - date + (version). That should make display more consistent and hopefully make it easier for things like IRLDB to have useful output.
Comments on a postcard ... er, post, ... please. :-)
