Weapon timings?

I know the MLG timings off by heart. But, on Vanilla Reach I have no idea how it works and I cba to find out the long and boring way. I think they work like Custom does in MLG, but I’m not sure. Anyone know how they work?

i just know power weapons like fuel rod and rocket launcher are every 3 minutes after pick up

After playing on maps in MM, save the map variants and recon them in forge.

It does work like the powerup. Their timer always starts as you pick the weapon up, not when it actually spawns. The timer will not always be the same because the weapon will not always be picked up as it spawns.
