Hey @armando1793, thanks for the contribution, but we have implemented a more general and robust regular expression solution for detecting invalid formats. You can check out the upcoming changes outlined here: #612.

Feel free to take on some new issues though :). We are trying to re-invigorate arrow's development and need all the help we can get! As part of that process though, we are cleaning up some old issues and PRs.
