What does 86400 mean in physics?

Question

one of the guys at my work quoted this number to me (86400) and told me that if I could work out what it means/represents or whatever he'd give me ten bucks. I'm just not allowed to ask anyone else at work.

please help?

also I work in a IT company and he used the number when setting up DNS... could it possibly have a different meaning in this context?
