hudakz 3:5b17e4656dd0 3 *
hudakz 3:5b17e4656dd0 4 * The clock interface is the interface between the \ref timer "timer library"
hudakz 3:5b17e4656dd0 5 * and the platform specific clock functionality. The clock
hudakz 3:5b17e4656dd0 6 * interface must be implemented for each platform that uses the \ref
hudakz 3:5b17e4656dd0 7 * timer "timer library".
hudakz 3:5b17e4656dd0 8 *
hudakz 3:5b17e4656dd0 9 * The clock interface does only one this: it measures time. The clock
hudakz 3:5b17e4656dd0 10 * interface provides a macro, CLOCK_SECOND, which corresponds to one
hudakz 3:5b17e4656dd0 11 * second of system time.
