I am trying to do something as close to "real time" as possible. Using a system call (IMHO) just adds overhead.
I comme from an embedded application world and every microprocessor I ever wrote assembly language on could read the RTC directly. I don't need to convert that "time" into anything humanly usable. I just want a 32 bit number that ticks up at a constant rate with as little overhead as possible.
Why is this so hard ?
