1. A method, comprising executing computer executable instructions by one or more processors for monitoring and correcting sample time stamps, the method further comprising:
receiving, by a router or a switch, Internet Protocol (IP) data from one or more sensors or intelligent electronic devices (IEDs), wherein the one or more sensors or IEDs are operable to monitor and revise data time stamps; examining, by the router or the switch, time stamps associated with the received Internet Protocol (IP) data; performing, by the router or the switch, deep packet inspection of the received Internet Protocol (IP) data; determining, by the router or the switch, a variance between the time stamps or an offset between the time stamps and an accurate time source; revising, by the router or the switch, at least one time stamp of the received Internet Protocol (IP) data, based at least in part on the determination; reporting, by the router or the switch, the variance or offset to other devices that utilize the datagram data; and sending a time-reset command to one or more of the sensors or IEDs when the variance or offset meets or exceeds a predetermined threshold. |
