ABSTRACT:
An embodiment of a digital recording apparatus real-time clock is disclosed. In particular, a real-time clock to mark when each recording is taken is described. The embodiment comprises a digital recording apparatus that contains a real-time clock powered by the main battery of the digital recording apparatus. The real-time clock resets when the digital recording apparatus's batteries are removed. When a recording is made, the digital recording apparatus marks the recording with the current value of the real-time clock, e.g., seconds since the batteries were changed. A computer then reads the media recorded by the digital recording apparatus and provides a date and time reference to which to relate the digital recording apparatus's real-time clock.
