Detailed Description

Date (year, month, day in month)

Date class is a chrono::time_point<std::chrono::system_clock>.

Date represents the date with year, month and day in month. The basic date (local time) is from your operating system.

[Inherited]

A time_point object expresses a point in time relative to a clock's epoch.

Internally, the object stores an object of a duration type, and uses the Clock type as a reference for its epoch.
