Utility meter with enhanced clock accuracy

An electronic power meter for monitoring power usage of an electrical circuit comprising:

• a housing;
• at least one sensor connected to the housing and configured to be connected to an electrical circuit, the at least one sensor configured for measuring at least one power parameter of the electrical circuit and generating at least one analog signal indicative of the at least one power parameter;
• at least one analog to digital converter connected to the at least one sensor, the at least one analog to digital converter configured to receive the at least one analog signal and convert the at least one analog signal to an at least one digital signal to obtain measured data;
• a processing system including one or more processors, the processing system configured for receiving the at least one digital signal and performing at least one calculation based on the received at least one digital signal to obtain calculated data;
• memory connected to the processing system, the memory comprising at least one memory location, the memory configured to store the measured data and the calculated data,
• wherein the processing system includes a real time clock emitting a clock signal and a temperature sensor emitting a temperature signal, and wherein the processing system is configured to analyze the clock signal and the temperature signal to detect a deviation in the clock signal and to apply a trim value to the clock signal if a deviation is detected to obtain a corrected time data.
