A clock control method for managing clock between two endpoints, a clock control system, and a computer readable media are provided to synchronize a clock by shifting a reference line based on delta between packets. A transmitting device(110) transmits a first packet to a receiving device(120). The first packet is received by the receiving device and an extracted time stamp. The time stamp is used in order to set up an initial reference line. The packet is transmitted from the transmitting device to the receiving device. A clock managing module(150) determines deviation from the reference line. If delta is a negative number, the reference line is updated as amount of the negative number. If delta is a positive number, a minimum positive number delta within a present window is stored. The clock managing module determines rate of a reference line deviation about elapsed time.
