There is provided a GNSS independent method for asymmetry delay error compensation to minimize a time difference bias when using two-way time transfer in a communication network. The method includes establishing a bidirectional virtual path comprising at least one link path, LP-LP, over the network for communication between a first node A and a second node B by sending a bidirectional data stream over the virtual path and utilizing previously stored link profiles associated with a delay correction factor or a calibrated virtual path or a stable local clock in holdover mode to provide new delay correction factor to minimize a time difference bias in the local time in the second node.
