[1.7.10]Is there any way to test what the time left is on a potion effect?

I cant find any way to do this, hopefully you can. If it helps i want to test the time left for the player.

Thanks! its working now. The reason i wanted to test for the durability was because i wanted to make something happen when the potion effect runs out. Unfortunately if you clear the potion effect by dying or drinking a milk bucket etc... it obviously doesn't work. Is there any way to test when a potion effect is cleared?
