- Obviously, `tim` is a typo for `time`
- This didn't cause an exception because IO#raw is implemented in C and it doesn't check the keyword of the parameters
- Though this typo doesn't produce any problems for now, I think it should be fixed just in case for the future
- I've used this fixed version of Reline with IRB for several days and didn't find any new problems due to the fix
- But I myself am not sure how to make sure this fix is completely robust
