If rep_ is a member variable holding the number of ticks in a duration object,
1) Equivalent to

2) a copy of this duration object, with the number of ticks negated
Example
#include <chrono>
#include <iostream>
int main()
{
std::chrono::seconds s1(10);
std::chrono::seconds s2 = -s1;
std::cout << "negated 10 seconds are " << s2.count() << " seconds\n";
