Abstract
Certain embodiments of the invention may include systems, methods, and apparatus for modifying sensor time stamp data. According to an example embodiment of the invention, a method is provided for monitoring and correcting sample time stamps. The method can include receiving packet data from one or more sensors or intelligent electronic devices (IEDs); examining time stamps associated with the received packet data; and determining a variance between the time stamps or an offset between the time stamps and an accurate time source.
