This file implements a function Clock, a timer with millisecond precision. In order to obtain timing at high resolution, platform- specific functions are needed:

Otherwise as a fallback, time.h time is used, and in this case Clock has only second accuracy. This file attempts to detect whether the platform is POSIX or Windows and defines Clock accordingly. A particular implementation can be forced by defining USE_GETSYSTEMTIME, USE_GETTIMEOFDAY, or USE_TIME.
