CLOCKS_PER_SEC

Expands to an expression (not necessarily a compile-time constant) of type std::clock_t equal to the number of clock ticks per second, as returned by std::clock() .

Notes

POSIX defines CLOCKS_PER_SEC as 1 '000' 000 , regardless of the actual precision of std::clock() .

Example

#include <ctime>
#include <iostream>
#include <locale>
int main()
{
    const std::clock_t cps{CLOCKS_PER_SEC};
    std::cout.imbue(std::locale("en_US.utf8"));
    std::cout << cps << '\n';
}

1,000,000
