7.6. Stopwatch: Timer with Microsecond Accuracy

(lsh/libc/stopwatch.lsh)

stopwatch is a simple class to measure time with microsecond accuracy. This does not generate events (see the timer/event section for that), but merely provides a way to tell time. This class uses the gettimeofday system call and can be used in compiled code.

[MSG] (lsh/libc/stopwatch.lsh)
