Alright, this is a quirky little question — 'commcan millis hours' sounds like a typo, but if we take it to mean the idea of dividing hours into milliseconds (or asking who invented milliseconds and why), the story is way older and more human than you’d expect.
People didn’t invent the hour one day and then invent the millisecond the next; timekeeping evolved. The basic concept of an 'hour' goes back thousands of years: ancient Egyptians split the day into 24 parts using sundials and star clocks, and Babylonian sexagesimal (base-60) math led to dividing hours into smaller chunks we now call minutes and seconds. Medieval and Renaissance Europe added mechanical clocks that made regular hours actually useful in daily life. The medieval hour didn’t look like our rigid 60-minute hour at first, but over centuries the notion of fixed-length hours, minutes, and seconds crystallized.
The 'millisecond' is a much more modern convenience — it’s simply one thousandth of a second, born from the needs of precision science, industry, and later electronics. As telescopes, chronographs, telegraphs, and then radio and high-speed photography demanded ever-finer timing, scientists and engineers started talking in milliseconds (and microseconds, nanoseconds) to describe events that are imperceptible to human senses. Christiaan Huygens’ pendulum clock (17th century) tightened things up for seconds; by the 19th and 20th centuries, precise chronometers and electrical timing allowed subdivisions into milliseconds reliably. Atomic clocks and the adoption of the second as a defined SI unit (based on cesium transitions) made it meaningful to count tiny slices like milliseconds worldwide. Practically, milliseconds matter for astronomy, navigation, telecommunications, music tech, and gaming latency — anywhere timing affects outcome.
If you were secretly asking for the math instead: one hour contains 3,600 seconds, and each second is 1,000 milliseconds, so there are 3,600,000 milliseconds in an hour. I love that calculation because it bridges the ancient human habit of marking hours with sundials and the modern obsession with micro-precision when syncing networks or chasing framerates in games — same idea, wildly different scales.

Okay, so if you’re tossing around the phrase 'commcan millis hours' in a script, I usually read that as a shorthand for working with different time units or timing primitives — like a command-centric workflow where you pick between milliseconds for precision and hours for scheduling. I lean on milliseconds when I need tight control: animations, debouncing button presses, sensor sampling, timeouts for network calls, or anything where the difference between 10 ms and 100 ms matters. On microcontrollers you’ll see functions called 'millis()' all the time (Arduino folk, wave your hands). In desktop or web scripting, using high-resolution timers or performance.now() / process.hrtime() helps you measure intervals without being fuzzed by wall-clock adjustments.
For anything human-facing or long-running I switch to hours (or days, minutes) — cron-like jobs, backups, data retention policies, subscription expirations. Hours are easier for config files and for people reading logs: saying "run every 6 hours" is clearer than "run every 21600000 ms." Also, when your script sleeps or schedules tasks at long intervals, using hours avoids awkward large integers and reduces overhead from frequent wake-ups. I’ll usually convert to the smallest unit needed internally (millis for precision), but store and display durations in hours when it makes sense for maintainability.
A few practical tips I’ve learned the hard way: use a monotonic timer for measuring elapsed time (don’t rely on system clock for intervals, because NTP adjustments or daylight savings can bite you). Watch for integer overflow in constrained environments when you convert hours to milliseconds. If you’re scripting in JS, prefer setTimeout for short delays and use setInterval carefully (or implement your own loop with setTimeout to avoid reentry). For embedded stuff, prefer non-blocking timers and avoid busy loops that poll every millisecond unless you truly need it. Lastly, document the unit expected in configs and APIs — nothing wastes time like a config file where half the team assumed seconds and the other half used hours. Try to be explicit, and your future self (and teammates) will thank you.

Funny little phrase aside, if you mean using millisecond-level timing (like millis() or performance.now()) versus coarser hour-level timestamps to drive animation, then yes — millisecond or higher-resolution timers absolutely improve animation timing accuracy. I tend to think of animation timing in two camps: time-based (where you ask “how much time passed since the last frame?”) and frame-based (where you assume a fixed number of frames per second). Relying on hours, or any coarse absolute timestamp, is brittle for anything that needs smooth motion. Millis-level measurements let you compute a real delta time, so movement scales correctly whether the device is chugging at 10 fps or humming at 144 fps.
In practice I use a mix of techniques. For browser stuff I prefer performance.now() over Date.now() because it's monotonic and sub-millisecond accurate; for embedded projects millis() is often fine but you must watch for rollover. The common pitfalls are using setTimeout/setInterval for precise timing (they're influenced by throttling and scheduler jitter) or accumulating unbounded deltas that explode when the tab was suspended. The usual fixes: clamp large deltas, use a fixed timestep for physics (update the simulation in consistent chunks and interpolate for rendering), or run a variable timestep for simple animations with easing. Also, use interpolation to smooth between fixed updates so visuals stay silky even when logic runs at a lower rate.
Other practical tips from my toolbox: prefer a monotonic clock to avoid jumps when the system clock changes; cap delta to something reasonable (e.g., max 100–200 ms) to avoid teleporting when coming back from sleep; and rely on platform-friendly loops — requestAnimationFrame on the web, display link on iOS/macOS, or a vblank-synced loop for desktops — to align with VSync and reduce tearing. If synchronizing with sound or external events, consider using the audio clock or a high-resolution hardware timer. Ultimately, millisecond (or better) granularity gives you control and predictability, but you also need the right loop structure (fixed vs variable timestep), clamping, and interpolation to turn raw accuracy into smooth perceived motion — I've learned that the hard way while porting a small game prototype between my PC and an old Raspberry Pi.

When you dig into the nuts and bolts of how animation is timed, milliseconds absolutely matter — but maybe not in the way you first think. At the most basic level, frame rate is frames per second: classic cinema and most anime are authored for 24 frames per second (fps). That means each frame is displayed for about 41.67 milliseconds. So yes, milliseconds are the atomic unit of how long each drawing or cel shows on screen, and if those durations wobble you notice judder or irregular motion.
I tend to nerd out on the production side, so let me break it down practically. Animators usually plan in frames, not milliseconds — saying “this shot holds for 12 frames” rather than “500 ms” — because the whole workflow (keyframes, in-betweens, exposure sheets) uses frame counts. But when footage is encoded, streamed, or played back, players and TVs use timecodes in milliseconds, and inconsistencies there (bad frame pacing) cause stutter. For example, uneven frame times — one frame 33 ms, next 50 ms, next 30 ms — will feel choppy even though the average might be close to 24 fps. Human perception is surprisingly picky: stable timing is often more important than raw fps.
There’s also the production-hours angle: the amount of time a studio has (the slog of deadlines and crunch hours) indirectly affects frame rate choices. Under tight schedules, a director might opt for ‘working on 3s’ (animation holds where the same drawing lasts three film frames, effectively 8 fps) or reuse cycles to save time. That’s why cheaper shows or rushed episodes feel visually stiffer — it’s not the milliseconds themselves, it’s the choices forced by limited hours of work. Conversely, special sequences or big-budget films might be cleaned up to smoother motion, use more in-betweens, or even include high-frame-rate CGI passes.
Finally, modern tech blurs things: TVs and players can apply motion interpolation, converting 24 fps into 60 fps or 120 Hz displays, and while some people love the smoother look, others hate the 'soap opera effect.' Also, when anime is converted between standards (24 -> 25 -> 30 fps), frame-duplication or pulldown introduces small timing artifacts. So in short: milliseconds do matter for perceived smoothness and for playback fidelity, and hours/stress during production shape how many frames an animator can afford. If you want to chase buttery motion, pay attention to consistent frame timing and, where possible, watch raws or high-bitrate releases and experiment with interpolation settings to suit your taste.
