1. A method for generating DTE, the method comprising: at a test device for testing a timing device:
configuring, using configuration information, a timestamp impairment engine for generating DTE values for transmit timestamps, wherein the timestamp impairment engine utilizes a sine wave based formula to generate the DTE values;
generating a packet comprising an impaired transmit timestamp, wherein the impaired transmit timestamp is generated using a non-impaired timestamp and a DTE value generated by the timestamp impairment engine;
sending the packet to the timing device;
analyzing performance of the timing device, wherein analyzing the performance of the timing device includes receiving and analyzing a response message associated with the packet; or analyzing a packet log or a timing data log associated with the timing device; and
reporting test results to a test operator or a test system.
