The invention provides a metering core clock processing method and apparatus for a dual-core intelligent electric energy meter. According to the metering core clock processing method and apparatus for the dual-core intelligent electric energy meter, a clock is obtained and then an effective initialized clock is obtained before the current clock is obtained, so that a judgment basis is provided for metering data after fault occurrence; and meanwhile, after an external clock is obtained, whether the external clock is abnormal or not is judged, so that a basis is provided for obtaining the effective and accurate current clock. The clock accuracy of the electric energy meter is ensured and a basis is provided for electric energy tariffing of subsequent time-of-use electricity price.
