duration& operator++();
(1)
(since C++11) (constexpr since C++17)
duration operator++( int );
(2)
(since C++11) (constexpr since C++17)
duration& operator--();
(3)
(since C++11) (constexpr since C++17)
duration operator--( int );
(4)
(since C++11) (constexpr since C++17)
Increments or decrements the number of ticks for this duration.
If rep_ is a member variable holding the number of ticks in a duration object,
1) Equivalent to ++rep_; return *this;.
2) Equivalent to return duration(rep_++).
3) Equivalent to --rep_; return *this;.
4) Equivalent to return duration(rep_--);.

[edit] Return value
1,3) A reference to this duration after modification.
2,4) A copy of the duration made before modification.
[edit] Example
