Join leap_seconds (https://youtu.be/WX3OmVu4lAs) • time_zone and time_zone_link (https://youtu.be/MODhhr7m-5s) • system_clock::now(), file_clock, leap second awareness (https://youtu.be/c7DT28TV0AY)9 Part II: Safety The “simple” calendrical types (e.g., day, month, year) are very straightforward – what’s the point in creating types for these concepts at all? Couldn’t we just use unsigned int for each
