Using ICoG from the Attendance event?

Quick thing, sorry about this. But, how do you determine when a server tick has happened. Basically, I just want to avoid a situation where I take out a scroll, and it's like 1-2 seconds away from a server tick. Or do you automatically get like 10 seconds after you take the scroll out of storage? And theoretically, could you take the scroll out of storage, and then quickly put it back in before the tick?

I don't have a method for this.

I think technically the game needs to register the item to be put into storage or something like that so no.
