set_normalized_timespec64(9)

✨ set_normalized_timespec64 ✨

okay so this is a page from the Kernel API Manual, bestie — set_normalized_timespec64(9) — and it's genuinely such a little icon. let's get into it 💅

---

🌸 NAME 🌸

set_normalized_timespec64 — sets the sec and nsec parts of a timespec and normalizes them. that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

void set_normalized_timespec64(struct timespec64 *ts, time64_t sec, s64 nsec);

---

💖 ARGUMENTS 💖

• ts — pointer to the timespec variable you're setting, bestie. that's the thing getting the glow-up ✨
• sec — the seconds you wanna set it to
• nsec — the nanoseconds you wanna set it to

---

🔥 DESCRIPTION 🔥

So what it does: it sets the <italic>seconds</italic> and <italic>nanoseconds</italic> fields of a timespec variable, then normalizes the whole thing into the timespec storage format. like, it takes your raw numbers and makes them presentable. main character energy fr fr 👑

---

⭐ NOTE ⭐

Listen up, this part is important 😭 the tv_nsec part is always in the range of 0 <= tv_nsec < NSEC_PER_SEC. and for negative values, only the tv_sec field is negative! not both. just the one. ik ik, iconic behaviour 💀

okay that's the whole page, you ate that 🫶 this one lives in ./kernel/time and the version/date sitch is October 2026 — so like, go set some normalized timespecs, bestie, and remember: only tv_sec gets to be negative. periodt 💜🌸
