# CLOCKS_PER_SEC

From cppreference.com
< cpp‎ | chrono‎ | c

Defined in header `<ctime>` |  |
#define CLOCKS_PER_SEC /*implementation defined*/ |  |

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().

### [edit] Notes

POSIX defines `CLOCKS_PER_SEC` as one million, regardless of the actual precision of std::clock().
