If you post it under, or with your issue, then pretty much anyone who sees the issue can approve.

Alright, who is going to see such forks and approve?

Alright I updated the message. When you have small improvements like this feel free to make a quick fork.

Yes, I eventually figured it out, but that wasted a lot of my time. And that test is not even accurate.
Better would be something like : no hardcoded date or time (sub)strings in your code

Doesnt it just mean you should have no date or time in your code? To avoid hardcoding? It seems you figured that out already though

What the heck does this error message supposed to mean? Are we doing a 7Kyu kata or some kind of puzzle?
no date/time in your code

this was a very good kata for newer people!

Ah, got it... Thanks

There is no sample test, only one main test, because it only one time in Japan now. What else would you like to tested?

In bash, there seem to be no test

Ruby Translation!

Please inspect and approve!
