General information about time_* inlines — the glow-up your timer code deserves 🎀

🌸 SYNOPSIS 🌸

These inlines deal with timer wrapping correctly. You are strongly encouraged to use them, fr fr:

Because if the timer wrap changes in future you won't have to alter your driver code.

that's it. that's the whole vibe check. iconic, honestly 💅

✨ DESCRIPTION ✨

So here's the tea ☕ — the time_* inlines are out here handling timer wrapping correctly for you. Like, they're literally doing the work so you don't have to 😭 and you are strongly encouraged to use them. Why? Two reasons, bestie:

  1. Because people otherwise forget — yeah, humans are gonna human 🙈 we forget stuff, it's giving main character energy, and these inlines just save you from yourself 💀
  2. Because if the timer wrap changes in future you won't have to alter your driver code — future-proofing! your driver stays cute and untouched while the underlying wrap logic can change under the hood. slay 🔥
