Steps to reproduce:

The repo I'm running it on is private so I can't share it.

Context and environment:

1. Skunk 0.5.1
2. Ruby 2.7.2

@mehagar Thanks for reporting this issue! Unfortunately I think this is an issue in rubycritic, could you please move it to the rubycritic project? I'm a contributor in that project but GitHub won't let me move it there.

I did some quick digging and I found that churn.rb:69 is not covered by any tests... so there is probably an issue there with ruby 2.7.2 and rubycritic 4.6.1.

Also, any chance you could add a debugger in that line and see what parameter it is trying to be passed to the process_date method?

@etagwerker @mehagar Can we close this issue then? Not sure if this is still a thing...
