ok now it works :)

Fixed

Sorry about that, not sure how such an error made it through. You'd think the test would fail.

Fixed now.

You can edit the sample tests yourself (until it gets fixed). It has no impact on full tests suite.

Exactly you are right. There is absolutely a typo. Shit, I spent 3 hours on this kata.

INDEED !!! There is a typo in both tests in C# instead of 14:51 there is 14.51.

C# has a typo in both the sample and full tests, 14.51 instead of 14:51.

Yep...

You are right i fixed that!

I believe this solution is not correct anymore as it is throwing OverflowException for the last test with number 89. Type int should be replaced with long.

This solution is incorrect. For example if the first word is "la" and the second is "tola" it returns 2, but according to the instruction it should return -1, because 'If the second string isn't a valid rotation of the first string, the method returns -1."

The condition should be: second.Length != first.Length
