When does Magento consider a cart to be abandoned? Where's that time limit set?

Question

If left to default settings, what circumstances would have to occur for Magento 1.7 to consider a cart abandoned? Where is the code that makes this determination located?

Answer 1

The question was about when a cart becomes abandoned, not when the quote expires. As Magento doesn't have abandoned cart functionality, it's arbitrary. The various extensions to add it let you set it.
