yep. I have some code to that effect in my own stuff...
the only gotcha is that that require a static initial value... since
the function in question give you tick since the begenning of the
program... so you need
to convert t=0 to a real time once and store it in a static variable
to be able to provide an emulation of clock_getttime

I'm concerned about static variable in ure... and how to properly and
racelessly initialize it...
