TICKS-PER-SEC). Perhaps not ideal to cons in a timing primitive where low overhead is = called for. What about just returning an integer and have a different way to get at = TICKS-PER-SEC? After all, the timer frequency is not specific to each measurement. Ideally the returned value should be a fixnum to minimise overhead, but = it may restrict the range on 32-bit platforms. I also agree with Phillipp's comment about clock_gettime.
