Hi, i have this code and wanted to make timestamps in millisecond, but shows no millisecond values. This is for fast measurements with timesteps inferior to 1s. I wanted to attach this file but firewall blocks, so i paste it, there is nothing sensible on it. ```auto //Environment settings clear(); path=["C:\Users\buehlpas\Desktop\Messungen\"]; name=["Test"]; ending=[".csv"]; header=["Time","one","two","three","four","five","six","seven","eight","nine","ten"]; // Creating file to put datas in filename=fullfile(path+name+ending(1)); [unit,err]=file("open",filename,"new","sequential","formatted"); realtimeinit(0.5); realtime(0); for i=1:1:10 realtime(i) write(unit,strcat([string(datetime("now","OutputFormat","yyyy-MM-dd HH:mm:ss.SSS")),string(1:10)],',')); end file("close", unit); //Reading the data-file body=csvRead(filename,",",".","string"); ts=timeseries(datetime(body(:,1)),strtod(body(:,2:$)),"VariableNames",header); stackedplot(ts); ``` ---

Hello Pascal, Indeed, it seems that datetime loses millisecond information during the conversion, I opened an issue which will be corrected in the next version 2024.1.0 of May 2024 > **[Timeseries and Milliseconds (#17223) · Issues · scilab / scilab · GitLab](https://gitlab.com/scilab/scilab/-/issues/17223)** > > Bug Description datetime("now") loses milliseconds information. Steps to reproduce ... ---
