I was playing around with benchmarking some of my code and found getTicks in lib/pure/timers.nim. It doesn't seem to be part of the default system and importing directly won't work because nothing in timers.nim is public. So I ended up just grabbing the file and putting it in my own project for the moment.
Is there a better way?
I've also been playing around with benchmarking today and am hoping that this will lead to a Nim benchmarking library as described in the GSoC project here: https://github.com/Araq/Nim/wiki/GSoC-2015-Ideas#benchmarking-library
Linux only so far: https://github.com/def-/nim-bench/blob/master/tests.nim
The timers module you found seems to be meant for including, not importing, because it exports nothing.
