How to add a timestamp to array in simulink?

Hello,

I have problem with adding a timestamp in simulink. I have array date (9 values) from IMU sensor like on the picture and I need to add a tenth kolumn with timestamp (with milisecond).

I have tried like on the picture below with code in matlab function:

    function [Y, M, D, H, MN, S, MS] = fcn()
       eml.extrinsic('now');
       eml.extrinsic('datevec');
       Y = 0;
       M = 0;
       D = 0;
       H = 0;
       MN = 0;
       S = 0;
       MS = 0;
       [Y, M, D, H, MN, S, MS] = datevec(now);
    end

And to create a file with txt format I used a command:

dlmwrite('E:\temp.txt', sumout111,'delimiter','\t','precision',3)

When I run simulation I have error:

Ok, I have changed directory and ran as admin Matlab and I have another problem:

1. If you want to run the model as a regular user, you can set the cache folder to some folde other than C:\Windows... Example:

set_param(0, 'CacheFolder', 'D:\Temp')

2. If you want to run as Admin, after the \MATLAB opens up, do mex-setup and select host compiler(lcc or MSVC++) : Reason: For each profile, the mex settings are stored separately.

It works. Thanks a lot.

And I had to delete 'MS' from code because datavec returns only 6 values. Datevec returns milliseconds as a fractional part of the seconds (S) output (for example 15.6).
