Back in DotA 1, if Darkterror caught an unit affected by a slow/stun in Chronosphere, the slow/stun timer would pause, meaning the hero would be stunned/slowed for the remaining of its duration after chronosphere duration, due to the pause mechanic of Warcraft.
Not so long ago, I heard Dota 2 Chronosphere now work as a big AoE stun instead of pausing any buff/non-doom debuff duration. Is it true?
