You can now see how you can use the now method to compare two time_points and it’s not much more of a stretch to imagine that you can create an if statement that only executes once a certain amount of time has passed. Recipe 2-8. Understanding lvalue and rvalue References Problem C++ contains a distinction between an lvalue reference and an rvalue reference. You need to be able to understand these concepts to write optimal C++ programs. Solution Modern C++ contains two different reference operators, & (lvalue) and && (rvalue).

The epoch is a reference time that the system uses to offset all other times. You will not have to worry about the epoch by using the same clock for all of your time work. However you will have to be aware that a time from one computer may not be transferrable directly to another if the systems use different epochs for their time. The time_point structure cannot be printed out directly and there is no method to convert it to a string however the class does provide a method to convert the time_point object into a time_t object.

M_Member = nullptr; } int GetValue() const { return *m_Member; } }; int MyClass::s_Counter{ 0 }; MyClass CopyMyClass(MyClass parameter) { return parameter; } int main() { auto object1 = MyClass(); { auto object2 = MyClass(); } auto object3 = MyClass(); auto object4 = CopyMyClass(object3); return 0; } 47 Chapter 2 ■ Modern C++ The code in Listing 2-30 adds a move constructor to MyClass. This has an immediate impact on the running code. You can see that the move constructor is being invoked in Figure 2-10.
