In NHL the current standard is 0.5 secs, anything over that can/will be ruled late.
Let Bob McKenzie explain that to you:
There's no question in my mind that there will be a suspension for Aaron Rome because his hit on Nathan Horton was late. The National Hockey League has a standard, and that standard is any hit beyond half a second after the player has released the puck leads to an interference penalty. This was almost a full second.

Jenner's hit was OVER 1 second after the release. It resulted an injury.
If Aaron Rome got 4 games for the hit on Horton, how can anyone call out IIHF for this one? Later hit with tournament-ending injury in a pre-tournament game? If anything, one could argue that Jenner should have gotten more.
