Hello everybody!! I'm learning some stuff here, and I have to ask.. what does "TO" means?

Welcome to the community! I'm fairly new myself, so I don't know all the acronyms, but I might be able to help you figure it out if you put where you found it. EDIT: I think it's overtime, unless it's meaning something else.
