(B2) used to say that you do not know exactly when something will happen, but you are certain that it will happen.

Sooner or later she's going to realise what a mistake she's made.

Không sớm thì muộn cô ấy cũng sẽ nhận ra lỗi mà cô ấy đã gây ra.

For example, suppose a block solution is a number that ends with 10 zeros and, a share may be a number with 5 zeros at the end. Sooner or later one of the shares will have not only 5, but 10 zeros at the end, and this will be the block solution.
