Removing cron code from footer?

[sross]

No matter what I try with my style my footer goes funny when the code for the cron is in there. It's as if a cell expands then when you refresh it goes back to normal. I've tried everything to stop this from happenening and the only solution was to remove this code. So what does this mean not having the code in there? Everything has been running fine, so what exactly do I need it for? thanks!
