C++ includes support for two types of time manipulation: The chrono library, a flexible collection of types that track time with varying degrees of precision (e.g. std::chrono::time_point). C-style date and time library (e.g. std::time). [edit] std::chrono library The chrono library defines three main types as well as utility functions and common typedefs: clocks, time points, durations. [edit] Cl

signed integer type with width of exactly 8, 16, 32 and 64 bits respectively with no padding bits and using 2's complement for negative values (provided if and only if the implementation directly supports the type) (typedef) [edit]
