When using /give to obtain tipped arrows with custom effects, the effect duration renders ten times smaller in the tooltip. Any duration below ten seconds renders as (0:00), ten seconds renders as (0:010, etc. etc. This can be reproduced using the command below.

/give @p minecraft:tipped_arrow 1 0 {CustomPotionEffects:[{Id:2,Amplifier:0,Duration:200},{Id:19,Amplifier:0,Duration:200}],Potion:"minecraft:mundane"}
