System Time

Post by CNC_Machines » Thu Feb 06, 2020 3:37 pm

Greetings,

I am wondering what happens when a KFlop is left on for a very long time. Specifically, does the function Time_sec() run into any problems. For example, lets say a machine hasnt been rebooted for several months. Will this function max out when it runs out of memory? Is there a way to zero it out again without rebooting the machine?

Thanks,

Scott

Hi Scott,

That shouldn’t be an issue. Time_sec() is a double precision floating point value with 52 bits of precision (more than 16 digits). And so will still be accurate to a microsecond after a hundred years. Counting doesn’t consume memory.

Yes, double precision avoids so many nasty issues. :)
