PURPOSE: A time stamping apparatus at a physical layer and a method thereof are provided to offer time stamping having high accuracy through simple algorithm without amending network configuration, and to reduce delay, jitter, and uncertainties produced in a process of time stamping. CONSTITUTION: A first time stamping unit(10) products a time stamp after inserting a marker into a synchronizing packet at a physical layer based on a sequence ID of a time sync packet. A second time stamping unit(20) produces the time stamp after confirming the time sync packet through the marker of the packet which is received at the physical layer by receiving packet from the terminals connected to network. |
