Elegant way to time function execution

Elegant way to time function execution

[Christopher Baines]

So I have managed to get something working with srfi-19, but the output
is not very readable:
 #<time type: time-duration nanosecond: 1482337000 second: 0>

I tried a couple of ways to make this human readable, but before I write
something myself, I thought I would check if anyone knows of some
existing code to make time durations human readable?

Thanks,

Chris

You may try time-utc->date or it's friends to convert seconds to
Y/M/D/h/m/s. But you may need to write a function to print each field.
BTW, ",a" command in the REPL is your friend when you have no any clue
about what function may work.

Best regards.

Like translating 60 seconds to the string "one minute"?

Reading SRFI 19, I can't be sure, but I suspect that it's supposed to be
an error to use a "time-utc->..." procedure on a time object with type
"time-duration".

The easiest way to make a time-duration type of time object readable
that I can see is turning it into plain seconds via:

    (+ (time-second t)
       (/ (time-nanosecond t) 1000000000))
