Description
A tick_count::interval_t represents relative wall-clock time or duration.
Members provide for the accumulation and reduction of intervals by other interval_t values, and for the conversion of interval_t values into seconds.

interval_t() Effects: constructs an
interval_trepresenting a zero time duration.-
doubleseconds()const Returns: a time interval measured in seconds (can have noninteger values).
-
interval_t operator+=(const interval_t&i) Effects:
*this = *this+i.Returns: a reference to
*thisafter the addition.-
interval_t operator-=(const interval_t&i) Effects:
*this = *this -i.Returns: a reference to
*thisafter the subtraction.-
interval_t operator+(constinterval_t&i,const interval_t&j) Returns: an
interval_trepresenting the sum of intervalsiandj.-
interval_t operator-(constinterval_t&i,const interval_t&j) Returns: an
interval_trepresenting the difference between intervalsiandj.
