The "/effect" command sets time for instant effects to ticks and not to seconds

When the new saturation effect came out, I used command blocks to give me hunger points. It seemed like at amplifier 0 for 1 second I got 1 hunger point. When I put the same effect on a potion using NBT editors, even 1 second at amplifier 0 filled my entire hunger bar, when it should act the same as /effect. The issue is that when the command says the effect was applied for x seconds, it was actually applied for x ticks.
