Abstract
An advanced metering infrastructure (AMI) system includes a meter data management system, an AMI network, a network communication module and metering devices. The AMI network connects to a reference time clock and the meter data management system. The network communication module connects to the AMI network and is in communication with the reference time clock via the AMI network. Each metering device is connected to the network communication module and has a metrology device and a communication module device. The communication module device provides clock adjustments to the metrology clock and/or its own clock. The metrology device provides clock adjustments to the communications module clock and/or its own clock. Methods for use in an advanced metering infrastructure (AMI) system provide clock adjustments.
