how to get down to seconds on org-clock measurements?

[Filipe Silva]

With C-c C-x C-i and C-c C-x C-o we can get measurements on how much time
we spend on tasks:

:LOGBOOK:
CLOCK: [2016-11-21 Mon 22:50]--[2016-11-21 Mon 22:57] =>  0:07
CLOCK: [2016-11-21 Mon 22:30]--[2016-11-21 Mon 22:30] =>  0:00
:END:

But the smallest unit is a minute. How can we get measurements in seconds?

thanks in advance
