VFS_TIMESTAMP(9)

📦 version 15.1, in freebsd 14.5, freebsd 15.1, nixpkgs unstable

💖 NAME 💖

okay bestie, this is the VFS_TIMESTAMP(9) page from the Kernel Developer's Manual, and it does exactly one iconic thing: vfs_timestamp generates the current timestamp. ✨

🌸 SYNOPSIS 🌸

#include <sys/param.h>
#include <sys/vnode.h>

void
vfs_timestamp(struct timespec *tsp);

🦋 DESCRIPTION 🦋

so vfs_timestamp() is the little function that fills in tsp with the current time. that's it, that's the whole job, and it eats. 💅

the precision you get is based on the value of the vfs.timestamp_precision sysctl variable, and the levels are giving:

  • 0 — seconds only; nanoseconds are zeroed.
  • 1 — seconds and nanoseconds, accurate within 1/HZ.
  • 2 — seconds and nanoseconds, truncated to microseconds.
  • ≥3 — seconds and nanoseconds, maximum precision. 🔥

🎀 AUTHORS 🎀

this manual page was written by Chad David <davidc@acns.ab.ca>. iconic of him, honestly. 🫶

that's the whole page, bestie: Debian source/version, dated November 21, 2001, and the manual page is VFS_TIMESTAMP(9). no cap, you're now timestamp-literate. 💖✨
