Flip your premise around a bit: what kind of world do you live in where "obscure code" makes it to a production environment after hours? Do you not do code reviews to ensure good quality? Do you not test your releases before launch? Do you not have a release strategy that allows you to launch code when people are in the office? Why aren't you fixing that rather than blaming your coworkers?
