✨ ADJTIMEXCONFIG ✨

okay so bestie, we're in the System Manager's Manual section 8 and this page is all about adjtimexconfig — aka the little script that finds your kernel clock variables and saves them for reboots 💖

🎀 NAME 🎀

adjtimexconfig — find kernel clock variables and save for reboots ✨

🦋 SYNOPSIS 🦋

/usr/sbin/adjtimexconfig

💅 DESCRIPTION 💅

okay so here's the vibe. This script uses adjtimex(8) to hunt down the values for the kernel variables tick and frequency that will make your system clock approximately agree with the CMOS clock. approximate, bestie, we said what we said 💀

Then it saves those values in the config file /etc/default/adjtimex so the settings get restored on every single boot — specifically when /etc/init.d/adjtimex, or the systemd adjtimex.service, runs. main character energy for your boot sequence, fr fr 👑

Also, adjtimexconfig uses the drift rate recorded in /etc/adjtime to adjust the times it reads from the CMOS clock. so like, it's not just raw-dogging those reads, it's using the drift info you already gave it 🫶

If you notice your CMOS clock has a systematic drift (ugh, relatable, it's giving unreliable), then go read the clock(8) or hwclock(8) manual page, modify /etc/adjtime as required, and run adjtimexconfig again. rinse and repeat until it slays 💖
