New proposal: --- [...] components are not restricted to their normal ranges and will be normalized, if need be. For example, consider a struct tm initialized with a tm_year = 122, tm_mon = 10, tm_mday = 30, tm_hour = 22, tm_min = 57, and a tm_sec = 0. Incrementing tm_min by 13 and calling mktime() would lead to a tm_hour = 23 and tm_min = 10. This normalizing can lead to cascading changes: Again using a struct tm initialized as in the above example but with a tm_hour = 23, the same change would lead to a tm_mon = 11, tm_mday = 1, tm_hour = 0, and tm_min = 10. Negative values may also be normalized with similar cascading effect such that e.g., a tm_hour of −1 means 1 hour before mid‐ night on the previous day and so on. --- ? -Jan
