idpf_ptp_adjtime(9)

🌸 NAME 🌸

hey bestie, meet idpf_ptp_adjtime from the Kernel API Manual — its whole iconic job is to adjust the time of the clock by the indicated delta. that’s the vibe: clock gets a little nudge, delta says how much 💅✨

---

🦋 SYNOPSIS 🦋

int idpf_ptp_adjtime (struct ptp_clock_info *info , s64 delta );

---

🎀 ARGUMENTS 🎀

• info — the driver's PTP info structure. this is the PTP backstage pass, the structure the driver hands over so the function knows what’s up 💖
• delta — Offset in nanoseconds to adjust the time by. yes bestie, the time adjustment is measured in nanoseconds ⏱️✨

---

🔥 RETURN 🔥

0 on success, -errno otherwise. so like: zero = we ate and everything is iconic 👑; anything else = -errno is running the group chat, and that means error-code energy, fr fr 😭
