Yes. I found that issue and change the function to pure form which receives time as input argument.

When I tried to code in C++, I found myself coding in C only to feed the sources to g++.

I found myself coding in do-block for majority of Haskell code now. :-(

Thanks Yeoh!

I changed the code like belows and it works.

On a higher-level, you might want to reconsider the design of that function called parseHeader.

It has type: (a -> IO b) only because there's a special case "now" which apparently requires querying for the current time. Other than that, it's a pure function.

Is there a way to make it a pure function?
