stmmac_adjust_time(9)

💅 stmmac_adjust_time(9) — from the Kernel API Manual, bestie

okay so welcome to the manual page for stmmac_adjust_time, straight out of the Kernel API Manual. yes we're in kernel-land. yes it's hot. let's get into it 🫶

---

🌸 NAME

stmmac_adjust_time — (the original literally just leaves this blank, which is SO mysterious of it, honestly iconic 😭 the description is in DESCRIPTION, keep scrolling)

---

✨ SYNOPSIS

int stmmac_adjust_time (struct ptp_clock_info *ptp , s64 delta );

like, that's the whole signature. short king energy 👑

---

🎀 ARGUMENTS

• ptp — a pointer to the ptp_clock_info structure. that's your clock-info situation right there ✨
• delta — the desired change, in nanoseconds. how much do we want to shift by? that much. exactly that many nanoseconds 🕰️

---

🦋 DESCRIPTION

this function will shift/adjust the hardware clock time. that's it, that's the whole vibe — it nudges the hardware clock in time by the amount you asked for 💫

🌈 SEE ALSO

bestie the cross-references are giving a whole friend group, look at them all:

• the kernel file ./drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c 🔥

ngl if you're messing with the hardware clock, go read the whole little family above. they're all in ./drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c together, main character energy fr fr 💜

and that's the page!! sourced from ./drivers/net/ethernet/stmicro/... (the kernel tree path up there ⬆️), dated October 2026, and the whole thing is filed under stmmac_adjust_time(9). mwah, study it, slay, periodt 💅🎀✨
