It should even impact other skins as well when in tick-based timing mode. I would bet more users of xnpod_ns2ticks() may have overseen this rounding issue - like RTDM did. > Wouldn't it be better to round up the ticks instead of round it down? Hmm, probably. Mind to work out a patch for xnpod_ticks2ns()? What do others think about this issue? Can/should we change the rounding behaviour at nucleus level? Thanks for reporting, Jan
