PURPOSE: A time stamping apparatus and a method for accurate synchronization in network timing are provided to implement accurate synchronization by accurately measuring a time of transmitting data and a time of receiving data. CONSTITUTION: A synchronous pulse signal generator(110) generates a pulse signal synchronized with a local clock of a data receiving unit from received data. A receiving time measuring unit(120) measures a time stamp value of a time of receiving data by using the pulse signal. A synchronous pulse signal generator is formed in a physical layer of a receiving unit. The receiving time measuring unit is arranged in an higher layer than the physical layer of the receiving unit. |
