Webchrono is the name of a header, but also of a sub-namespace: All the elements in this header (except for the common_type specializations) are not defined directly under the std namespace (like most of the standard library) but under the std::chrono namespace.

Instead, all count values are internally converted into the widest representation (the common_type for the internal count types) and then casted to the destination type, all conversions being done explicitly with …
WebMember type Definition clock: Clock, the clock on which this time point is measured : duration: Duration, a std::chrono::duration type used to measure the time since epoch : rep: Rep, an arithmetic type representing the number of ticks of the duration : period: Period, a std::ratio type representing the tick period of the duration [] Member function green bay packers nfl football teamWebA duration object expresses a time span by means of a count and a period. Internally, the object stores the count as an object of member type rep (an alias of the first template parameter, Rep), which can be retrieved by calling member function count.
