🦋 DESCRIPTION 🦋

okay so this function returns the number of nanoseconds on the local cpu's clock. that's it, that's the whole vibe.

but here's the tea you actually need to know: it's always monotonic when you're comparing on the same cpu — meaning it only ever goes forward, never backwards, no time-travel nonsense on her watch 👑.

however — and this is the important part, don't skip it — there may be some drift between cpus. how much drift? within about a jiffy. so if you're comparing timestamps across different cpus, lowkey expect them to disagree a lil bit. same cpu = slay and reliable. different cpus = it's giving slight chaos, but only by about a jiffy so like, calm down, it's fine 🫶
