Claim 0:
1. A method for changing an activation state of an interruption module for selectively interrupting at least one passive cathodic protection unit from a metallic structure, the method comprising the steps of:
enabling a global positioning system (GPS) receiver in data communication with a controller of the interruption module;
receiving GPS time via the GPS receiver from at least one global positioning system satellite in data communication therewith;
synchronizing a real-time clock time of a real-time clock in data communication with the controller to GPS time;
disabling the GPS receiver; and
changing the activation state of the interruption module if a predetermined activation state change time of the interruption module is between the local real-time clock time and the GPS time to selectively electrically couple or electrically decouple the at least one passive cathodic protection unit from the metallic structure.
