ABSTRACT:
The invention discloses a method and apparatus for time stamping data packets under controlled conditions. Embodiments of the invention eliminate or minimize the error, caused in existing applications, by the elapsed time between the moment of a data packet generation and a the transmission of the data packet. Embodiments of the invention insert an initial data value, in lieu of the time stamp, into the data packet. Embodiments of the invention delay time stamp insertion to just prior to data transmission. A time stamp is inserted in time stamp location, and using a set of correction equations, embodiments of the invention generate a final error checking value that is attached to the data packet. Embodiments of the invention insert a precision time stamp into the data packet and apply a correction to the error checking value. At the end of the processing of the data packet, the latter contains a time stamp that has been introduced with a high precision, and has a correct error checking value.
