I am also confused with 0b. Is it a hexadecimal number or a Greek number? In hexadecimal, B stands for 11, and in the Greek system, according to one of the comments in the clock’s website, 0 which is actually stands from 2, and stands for 9, so . I am not sure how Greek numerations work, so I don’t really know which of the explanations above is correct.
What do you think?
