okay so bestie, this is the Kernel API Manual page for mlx4_en_phc_adjtime(9), and it's giving hardware clock shift energy ✨. no cap, the whole page is short and iconic, so let's go 💅.

✨ NAME ✨

mlx4_en_phc_adjtime — Shift the time of the hardware clock 🕰️💖

🌸 SYNOPSIS 🌸

int mlx4_en_phc_adjtime (struct ptp_clock_info *ptp , s64 delta );

bestie, copy that signature exactly — spacing and all — because code does not care about our vibe, it cares about characters 💀.

🧚 ARGUMENTS 🧚

• ptp — ptp clock structure. that's the PTP clock struct in question, periodt.
• delta — Desired change in nanoseconds. literally the amount of change you want, in nanoseconds ⏱️.

🦋 DESCRIPTION 🦋

so the function adjusts the timer by resetting the timecounter structure. that's the whole move — no extra plot twists, no hidden DLC. it's shifting the hardware clock, and resetting the timecounter structure is how it does the thing. iconic behavior, honestly 💅.
