Defined in header <ctime>
struct timespec;
 (since C++17)

Structure holding an interval broken down into seconds and nanoseconds.

Contents

[edit] Data members

Member Description
whole seconds, the value is >= ​0​
(public member object)
long tv_nsec
 nanoseconds, the value is in range [​0​, 999999999]
(public member object)

The declaration order of tv_sec and tv_nsec is unspecified. Implementation may add other data members to timespec.

[edit] Notes

The type of tv_nsec is long long on some platforms, which is currently non-conforming in C++, but is allowed in C since C23.

[edit] Example

Run this code
#include <ctime>
#include <iostream>
 
int main()
{
    std::timespec ts;
    std::timespec_get(&ts, TIME_UTC);
    char buff[0x80];
