Hello all

I have a small question concerning timestamps and netCDF, I written the process although I do not get a timestamp written in the final netCDF file that is humanly readable I have followed this process

T=1:1:length(Data);
start_date = datenum('01-Jan-2010 00:00');
end_date = datenum('01-Jan-2010 02:00'); % the final timestamp is one less that the actual length of the Data
interval = 1; % Interval of recording
start_date = datenum([start_date]);
end_date = datenum([end_date]);
tstep = interval/24; % timestep set
date = datestr(start_date:tstep:end_date);
T=datenum(date);
% create netCDF
ncid = netcdf.create('myfile.nc','netcdf4');
dimidT = netcdf.defDim(ncid,'Time',length(T))
varid3 = netcdf.defVar(ncid,'Time','double',dimidT)
netcdf.close(ncid)

I have tried and omitted the final convection of

T=datenum(date);

But then the netCDF cannot write the the file

First how can i produce timestamp that are humanly readable for netCDF content Secondly is there a way to use the original T (length of Data variable) to generate a timestamp based on that length and an initial time?

Any suggestions welcome Thank you
