argh I clicked the wrong damn button
(define (jiffies-per-second) 10)
(define (current-jiffy)
(with-let *libc*
(let ((res (clock_gettime CLOCK_MONOTONIC)))
(+ (* 10 (cadr res)) (caddr res)

For awhile the thing currently called (*s7* 'cpu-time)
was returning the wall clock time by accident. I
think the r7rs.scm functions should be:
___
Cmdist mailing list
Cmdist@ccrma.stanford.edu
https://cm-mail.stanford.edu/mailman/listinfo/cmdist
Observation:
$ ./s7
λ (current-second)
0
λ (current-second) ; about a minute later
0
The definition in s7:
(define (current-second) (floor (*s7* 'cpu-time)))
Executing `(*s7* 'cpu-time)' about 1 second apart:
$ ./s7
λ (*s7* 'cpu-time)
0.009856
λ (*s7* 'cpu-time)
0.010111
