Calculate difference between two times when I export text file to excel

Hi, I am working on a time stamp program in matlab and I want to calculate the difference in times that I have registered with my program once I open the file in excel. Every time I try to subtract both times I get a #value! error in excel. Any help will be really appreciated.

Thank you

How are you writing the time stamps to excel? Are you writing them as strings, or as MATLAB datenum, or as MATLAB datetime objects, or are you converting datenum or datetime objects to excel numeric dates, or are you using writetable() of a table that contains datetime objects?

Hi Nicolas,

As Walter mentioned, please verify the data type of the variables.

If it does not resolve the issue, please send us the workflow you follow and a sample code to help us reproduce the issue.

Thank you,
