Webstd::chrono::system_clock Converts t to a time point type, using the coarser precision of the two types. If time_point has lower precision, it is implementation defined whether the value is rounded or truncated. Parameters t - std::time_t value to convert Return value A value of type std::chrono::system_clock::time_point representing t . Example
