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? -- Kim-Ee
