__timekeeping_inject_offset(9)

💖 NAME 💖

__timekeeping_inject_offset — bestie, this one adds or subtracts from the current time. That's it, that's the whole vibe. ✨

(FYI this page lives in the Kernel API Manual neighborhood, so you already know it's deep kernel lore 👑)

---

🎀 SYNOPSIS 🎀

int __timekeeping_inject_offset (struct tk_data *tkd , const struct
timespec64 *ts );

Two args, one int coming back at you. Iconic signature, no notes. 💅

---

🫶 ARGUMENTS 🫶

• tkd — a pointer to the timekeeper you wanna mess with. Literally the thing that's getting modified, so pick your target carefully bestie 🎯
• ts — a pointer to the timespec variable that's holding your offset. This is the amount, the delta, the whole reason you're here ✨

---

🌸 DESCRIPTION 🌸

Okay so the entire personality of this function is: it adds or subtracts an offset value from the current time. That's the tea ☕. Positive offset? Time goes forward. Negative? Back we go. The little timespec you handed over is the amount, and tkd points at the timekeeper taking the hit.

No cap, that's genuinely the whole description — it's a small function with main character energy, not a 40-option monster 🦋
