I've been trying to perfect my
PHP Catholic Calendar Generator, and found some odd behaviour in the mktime function - if the timezone is not specified, it will try to guess when to apply BST or DST, messing up the date comparison operations which need to be exact in a script like this - so I defined the timezone as UCT, which is not affected by BST or DST.
On a side note, the Catholic Calendar has more rules than a game of Yu Gi Oh, which makes for an interesting coding challenge.
On another side, maybe we could put together some sort of Demo Scene Calendar for 2014, featuring screen shots of some of our finest effects and demos from previous years. Just an idea.
