Hi!

is there a way to read from simulink the system time (not the simulation time)...I tried a code I had found in Matlab answers, however it doesn't work....

This was the matlab function that doesn't work:

function [Y, M, D, H, MN, S] = sysClock()

coder.extrinsic('clock');

Y = 0;

M = 0;

D = 0;

H = 0;

MN = 0;

S = 0;

[Y, M, D, H, MN, S] = clock;

end

Error: 'extrinsic function 'clock' is not available for standalone code generation. It must be removed to generate standalone code. It could not be eliminated because its outputs seem to affect the calling function. Fix this error by avoiding using 'clock' or making sure its outputs are unused.

PS: I also tried the 'now' function, but it does not work.
