Instead of meaning 5:30, the "half five" expression is sometimes used to mean 4:30, or "half-way to five", especially for regions such as the American Midwest and other areas that have been particularly influenced by German culture. Each residue class modulo n may be represented by any one of its members, although we usually represent each residue class by the smallest nonnegative integer which belongs to that class[2] (since this is the proper remainder which results from division). Complete the timeConversion function in the editor below. Z The phrase "about seven-thirty or eight" clarifies this. Greatly inspired by @Mr.Xcoder's 22-byter in the comment of the existing 05AB1E answer by @Emigna. {\displaystyle \mathbb {Z} /n} However, please refrain from exploiting obvious loopholes. ) [citation needed] With the advent of computer generated and printed schedules, especially airlines, advertising, and television promotions, the "M" character is often omitted as providing no additional information as in "9:30A" or "10:00P".
