Well, the definition should be moved to a .cpp file and it seems to me
then this function belongs into somethings like utils.hpp.
Also (more likely a followup, unless it would spare us creating a
utils.hpp?), std::crono could be used? I need to study it a bit, not
too familiar with it, so I am not sure (Frediano mentioned to me some
problem with that which I forgot).
(I am also fine leaving it as-is and fixing it in a followup
alltogether, as I can see some things snowballing for you and you need
to stop somewhere.)
