The present application discloses a time distribution device capable of providing a synchronized time signal to a plurality of end devices connected to the time distribution device with cables of various lengths. The time distribution device may receive a time signal, generate a time reference based on the received time signal, compensate the time reference for hardware delay, and overcompensate the time reference for a delay caused by a maximum cable length. Prior to being distributed to various end devices, each being connected with the time distribution device by cables of varying length, this overcompensated time reference may then be delayed by an amount based on the cable length connecting each respective end device such that the arrival of each of the synchronized time references at the various end devices is synchronized.
