First: Are you sure your T vector is in seconds? If so, your time list covers about 48 milliseconds around 01-Jan-1904 11:41:29. It makes more sense if T is in days since 1904-01-01.

Anyway, here is a way to do it:

dt = datetime(1904,1,1) + T; % Use T/24/3600 if T is really in seconds
dv = datevec(dt);

I recommend to work with datetime objects, which are very flexible. For instance, the time axis adustst automatically when you zoom in plots.

I am sorry for wrong information.

By Mistake, I have uploaded the wrong file.

Now I am upload the correct file please find the attachment.

Thank you for your valuable answer but I used following code and it is working.

T = T./86400;

dt = datetime(T+1904*365.24264707,'ConvertFrom','datenum')

I will also try your code

Thank you again
