Effect timer is not working properly

While editing the foods in the behaviour_pack/items

folder I noticed that adding an effect condition is timed in seconds.I think that this should be fixed as when adding the effect "instant_health" to a food itdoesn't give the fine control needed.

Example: A food with "instant_health" effect with the minimal time of 1 second fills my health bar really fast.

This problem makes it impossible for me to make my behaviour pack.
