Help me with this code

I wrote a code to pick a parameter from the data set.

The code can only read line and extract parameter desired from the dataset. However, I want the code to be able to use the timestamp so that the code can be useful for an incomplete dataset. Full dataset is attached.

• An example of the data is: *CPNFC 2006/01/02 00:00:00 fmin =[---- ] foE =[---- ] h'E =[---- ] foE2 =[---- ] h'E2 =[---- ] fzE =[---- ] fminE =[---- ] foE3 =[---- ] h'E3 =[---- ] fminEs =[---- ] foEs =[ E] h'Es =[ E] TYPES =[----- ] fbEs =[---- ] foEs-type2=[---- ] h'Es-type2=[---- ] fbEs-type2=[---- ] foEs-type3=[---- ] h'Es-type3=[---- ] fbEs-type3=[---- ] fxEs =[---- ] fEs =[---- ] fm2E =[---- ] fm3E =[---- ] fminF =[---- ] foF0.5 =[---- ] foF1 =[---- ] fxF1 =[---- ] M(3000)F1 =[---- ] h'F0.5 =[---- ] h'F =[ 230 ] foF1.5 =[---- ] h'F2 =[ ] h'F1.5 =[---- ] foF2 =[ 455 ] fxF2 =[---- ] M(3000)F2 =[ 146 ] foI =[---- ] fxI =[---- ] dfs1 =[---- ] dfs2 =[---- ] dfs3 =[---- ] dfs4 =[---- ] TYPEF =[----- ] fxI1 =[---- ] fxI2 =[---- ] fzF2 =[---- ] h'I =[---- ] hdF2 =[---- ] hpF2 =[---- ] hmF2 =[---- ] h'ox =[---- ] Zm =[---- ] ypF2 =[---- ] h'F1 =[---- ] Zd =[---- ] foI1 =[---- ] foI2 =[---- ] f1MUF =[---- ] f2MUF =[---- ]

Filename='CPNFC20060102.txt'; % runs fine
Data = importdata(Filename);
%
%Selecting cell Line every hour

for i=1:24;
    for j=1;
FreqLine{j,i}=Data{(i-1)*64+10,1};
    end
end
%
FreqLine=FreqLine';

% Spliting the cell to get character
for i=1:24
   for j=1;
FreqCharLn(i,:)=FreqLine{i,j};
end
end

% Picking the parameter value of interest(foF2) from the dataset
for i=1:24
 FreqStrg(i,:)=FreqCharLn(i,57:59);
end
% Convert string to number
FreqChar(FreqStrg == ' ')='0'  % replace empty spaces with zero
FreQ=str2num(FreqStrg) % Covert string to number
FreQ(FreQ==000)=nan; % Parameter is obatined
