Explore the full potential of C++ by mastering the standard library.

Become a C++ Programmer

The C++ standard library is a collection of all the tools and utilities available in C++. It received its latest update in 2017, known as C++17. The update introduces many new features that further optimize our code. This module will help us fully grasp C++ and use it to its full potential.

C++ Standard Library

The clock consists of a starting point and a tick. So you can get the current time with the method `now`.
 
- `std::chrono::system_clock`: 
\
System time, which you can synchronize with the external clock.

- `std::chrono::steady_clock`: 
\
Clock, which can not be adjusted.

- `std::chrono::high_resolution_clock`:
\
System time with the greatest accuracy.

`std::chrono::system_clock` will refer typically to the 1.1.1970. You can not adjust `std::steady_clock` forward or backward in opposite to two other clocks. The methods `to_time_t` and `from_time_t` can be used to convert between `std::chrono::system_clock` and `std::time_t` objects.

Here, we briefly discuss the different types of clocks in C++.
