A method for detecting time rollovers is disclosed. The method may include receiving time data including week data and second data and processing the time data to generate a first date. The method may include generating, based on the first date and an offset value, a second date and obtaining, when the second date is prior to a baseline date, a network date. The method may include assigning the network date as the baseline date and processing the network date and the first date to determine an updated offset value. The method may include storing the updated offset value as the offset value and determining, based on the network date, a system date.

Software-based time rollover detection

A machine includes a plurality of electronic controllers electrically connected to an electrical power source along a first electrical circuit through a first relay and along a second electrical circuit through a second relay. A relay controller is directly connected to the electrical power source along a third electrical circuit, and is in communication with the first relay and the second relay. The relay controller is configured to open or close the first relay or the second relay in response to a power requirement indication.
