You will discover an error when you write your tests, but that's fine. It's why you write tests. :-)

#validateTime:minute: is a poor name choice for a few reasons.

- there is no validation going on. Validation would report an error for invalid data. - there is nothing to suggest what the first argument is, the counterpart to "minute:".

- it doesn't suggest there will be a new Time ("Clock") created.

- it's a "verb phrase" saying it will *do* something rather than answer something (I'm being vague here. Sorry.)

I suggest #normalizedForHour:minute:.

It explains that it will normalize the values and that it will answer a normalized result (it still isn't great, as it doesn't explain what).

Perhaps better would be #newNormalizedForHour:minute:.

Thanks,

I think I found the error

and solved it

hour: anInteger minute: anInteger2
    ^ self new
        hour: (anInteger2 // 60 + anInteger) % 24;
        minute: anInteger2 % 60;
        yourself

instance side :

printOn: aStream
    ^ aStream
        nextPutAll: self hour asTwoCharacterString;
        nextPut: $:;
        nextPutAll: self minute asTwoCharacterString

and the tests are green

now time to sleep and tomorrow time to figure out how to add and substract minutes. As I remember it right you gave already the answer to me somewhere in our conversation
