std::chrono::system_clock::from_time_t

static std::chrono::system_clock::time_point from_time_t( std::time_t t ) noexcept;
(since C++11)

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.
