How about the following?

T = readtable('data.txt','HeaderLines',3,'ReadVariableNames',false);
T.Properties.VariableNames = {'TIME_BEGIN','TIME_END','TEMPERATURE'};
T.TIME_BEGIN = datetime(num2str(T.TIME_BEGIN),'Format','yyyyMMdd');
T.TIME_END = datetime(num2str(T.TIME_END),'Format','yyyyMMdd');
Time = reshape(T{:,{'TIME_BEGIN','TIME_END'}}',[],1);
Temperature = repelem(T.TEMPERATURE,2,1);
figure
plot(Time,Temperature)
ylabel('Temperature','FontSize',16)
