DIFFTIME(3P)

🌸 DIFFTIME(3P) — bestie edition 🌸

ok so this is a page from the POSIX Programmer's Manual and we're gonna talk about difftime 💖

✨ PROLOG ✨

okay real talk first, bestie, because this part matters 🫶

This manual page is part of the POSIX Programmer's Manual. But heads up: the Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the deets on Linux behavior. Or, plot twist, the interface may not even be implemented on Linux at all 😭 no cap.

👑 NAME 👑

difftime — compute the difference between two calendar time values ⏰✨

---

💅 SYNOPSIS 💅

#include <time.h>

double difftime(time_t time1, time_t time0);

---

🦋 DESCRIPTION 🦋

The functionality described on this reference page is aligned with the ISO C standard. And listen: any conflict between the requirements described here and the ISO C standard? Totally unintentional, fr. This volume of POSIX.1‐2017 defers to the ISO C standard, periodt.

The difftime() function shall compute the difference between two calendar times (as returned by time()): time1 - time0. that's it, that's the whole vibe 💜

---

🌈 RETURN VALUE 🌈

The difftime() function shall return the difference expressed in seconds as a type double. slay.
