The invention provides a clock adjustment method, device and system of an electric energy meter, and belongs to the technical field of electrical automation. The method comprises the following steps: adjusting a standard clock of adjusting equipment; sending an adjustment instruction to the target adjustment electric energy meter through the carrier link at the first moment, and receiving a receiving instruction returned by the target adjustment electric energy meter at the second moment; based on the first moment, the transmission time delay of the adjustment instruction, the second moment, the transmission time delay of the receiving instruction and the temperature compensation correction value, a time delay correction value needing to be adjusted is determined; and sending the time delay correction value to the target adjustment electric energy meter to correct the clock of the target adjustment electric energy meter. According to the invention, the accuracy of clock adjustment can be improved. 本发明提供一种电能表的
