Note that the ISO standard uses "tqmin" (with the "min" part as a subscript). One fact is that no one seems to be using "tc". I was actually the one who initially proposed to use "tc", but I can not recall anymore the reasoning behind that. Change the minimum time quanta unit from "tc" to "mtq" to follow what the majority of the industry does.
