below code might help you. you can ignore this code if you have another logic to read that data.
t = char(data(1:3:end));
t = datetime(t(:, 5:16), 'InputFormat', 'yyMMddHHmmss');
rf = cellfun(@(x) str2num(x(3:end)), data(3:3:end), 'UniformOutput', 0);
rf = cellfun(@(x) [x nan(1, 31-numel(x))], rf, 'UniformOutput', 0);
rf = num2cell(cell2mat(rf), 1);
ht = cellfun(@(x) str2num(x(3:end)), data(2:3:end), 'UniformOutput', 0);
ht = cellfun(@(x) [x nan(1, 31-numel(x))], ht, 'UniformOutput', 0);
ht = num2cell(cell2mat(ht), 1);
