Abstract

A clock stores time data indicative of time of operation of a power machine. A timing circuit provides a timing signal and a controller is coupled to a timing circuit and to a memory, which includes a plurality of memory locations. An elapsed time value is maintained, based on the timing signal, by the timing circuit, and a subset of a plurality of memory locations is intermittently updated with the elapsed time value.
