Radiation.
Since different objects have different heat conductivity and different temperatures and heat capacities, the time can vary without limit.
Thermal energy travels by conduction, convection, and radiation. Conduction occurs when two or more objects of different temperatures are touching each other. The heat flows from the warmer object to the cooler object, until the objects reach equal temperatures. Convection is the transfer of thermal energy through a moving liquid or gas. Radiation is the transfer of thermal energy though matter and space.

Until the objects touching have equal temperatures.
The transfer of energy between two objects at different average thermal kinetic energies (temperatures) is referred to as heat transfer. It is always called heat transfer, regardless of what kind of energy is being transferred.
Two objects must be touching and it has to transfer heat
