That part has remained unanswered. These literals are defined in the literals::chrono_literals inline namespace and are in scope when std::chrono is in scope. The elements in this header deal with time.

I'm trying to get string like this: [2014-11-25 22:15:38:449] (C++11) wall clock time from the system-wide realtime clock (class) steady_clock (C++11) monotonic clock that will never be adjusted (class) high_resolution_clock (C++11) the ... A std::chrono::year literal representing a particular year (function) Synopsis. C++11 has introduced the
Here's how you do it with this library. How can I do this? chrono is the name of a header and 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. You want to use the C++11 standard’s chrono library to generate a ISO8601-formatted timestamp as a std::string, e.g. This is done mainly by means of three concepts: Solution: You can use this function which uses std::put_time with a std::ostringstream to generate the resulting std::string. Clock must meet the requirements for Clock or be std::chrono::local_t (since C++20). It is implemented as if it stores a value of type Duration indicating the time interval from the start of the Clock's epoch.. I don't think many in the standards committee would claim this is a revolutionary addition; there are only a couple of classes that can be instantiated and a couple of free functions allowing us to cast between some of the representations of time. You can change std::chrono::milliseconds to std::chrono::nanoseconds or microseconds for even higher precision and add a second int and a for loop to specify for how many times to run the code.
2. (C++11) The
For this part I'm also going to use a second header-only library "chrono_io.h":
I spent a lot of time trying to google it, but I found only second-precision examples.
