clock[edit]

Syntax
#include <ctime>
clock_t clock( void );

The clock() function returns the processor time since the program started, or -1 if that information is unavailable. To convert the return value to seconds, divide it by CLOCKS_PER_SEC.

Note:
If your compiler and library is POSIX compliant, then CLOCKS_PER_SEC is always defined as 1000000.
