The engineers are using the word "steer."   Personally, I think graviton 
emitters are used to slow or speed up time, but you might be right..  :-) 

In any case, prior to this change, the SE clock [you can see it on the 
screen] would change without regard for the size or direction of the jump. 
 Now, time moves only forward and will speed up or slow down in small 
increments in order to reach the target time.
