Abstract

A system, method and device are provided for reducing consumption calculation errors caused due to time drift in an endpoint device. In one embodiment, the endpoint device transmits consumption data in response to a request for consumption data. The request generally includes a time period of the consumption data. The endpoint device adjusts the set of intervals based on the extent of the difference between the collection system time and the endpoint device time to obtain the most accurate intervals. The process for adjusting intervals can be implemented independently from time synchronization between the endpoint and collection systems. Further, the process for adjusting intervals does not result in updating the meter reading data that have been already logged and stored in the endpoint device.
