Hi Nur,
I believe that you are trying to read from a ".cdf" file using the "cdfread" function. However, You are not able to find the date and time in the array.
The code you are using for reading the ".cdf" file is correct and the date and time is in the first column, However, it is in "datenum" format as you have set the "ConvertEpochToDatenum" option to "true".
Use the code below to convert "datenum" format to "datetime" format which will give you an array of date and time,
t = datetime(cell2mat(data1(:,1)),'ConvertFrom','datenum')
you can concatenate this array of datetime type data with your original cell type data. A better way to concatenate will be to convert this array to table format along with the cell type data you got from "cdfread". A table data type is best to use when working with different data types.
datetimedata=array2table(t);
originaldata=cell2table(data1);
newdata=[datetimedata originaldata];
Also you can specify range of data by indexing in to the table:
newdata(:,1);
This will give all the rows for the first column of the table. you can edit this code as per your requirements.
I hope this helps you in your work.

Tushar
