How could I set TimeConstrained globally?

Question

I want to set TimeConstrained globally, I tried use $PrePrint as bellowed script:

$PrePrint = TimeConstrained[#,5] &;

But there's no effect, evaluation could not be aborted within given time.

So is there any way to do this? Thanks!

I found the solution in another topic here

SetAttributes[timecon, HoldAll]
timecon[new_] := TimeConstrained[new, 5]
$Pre = timecon;
