Infinite potion effect?

[freshhh]

I have noticed that when I set leaping and strength potion effects to food for 30mins, the potion effect will become infinite and show like this in the inventory screen : "XX:XX". Here's the line of code I've used to give the potion effect :

ItemFood)new Sub3( STAID3, 10, 5.0F, false).setAlwaysEdible().setPotionEffect(5, 1800, 2, 1.0F).setUnlocalizedName("STA3");

 

Sorry for the many threads, I'm still in the process of learning and you guys are helping me really good with that! And yes I have posted this before but in the wrong section.

Seems like the limit of these two potion effects lies around 27:20 (time) when they go higher than that time, they bug and become infinite.

It might be because the duration is stored as an integer, and 27:20ish is right around the signed integer max value (32767).  A negative duration is likely interpreted as being infinite.
