Bug introduced in 10.0.0, fixed in 10.0.2

In version 10 using this Front End option no longer gives useful output:

SetOptions[$FrontEnd, EvaluationCompletionAction->"ShowTiming"]

In version 7 the time to evaluate and render would be printed in the window frame (status area) of the Notebook. In version 10 even a long evaluation prints a small value. I can briefly see a larger number flash before it is overwritten by a small value.

  1. Why is the useful timing being overwritten by an apparently meaningless one?

  2. Is there a way to restore the old timing behavior? I am quite attached to this functionality.

As an example, evaluating this I can see a momentary flash of "Time: 3.xx seconds" before it is replaced with e.g. "Time: 0.06 seconds":

Plot[{BesselJ[1, x], BesselJ[2, x]}, {x, 0, 10},
 PlotPoints -> 1*^5, 
 Filling -> {1 -> {2}}

This has been fixed in 10.0.2. The longer time now remain in the status windows. On windows 7, 64 bit

SetOptions[$FrontEnd, EvaluationCompletionAction -> "ShowTiming"]
Plot[{BesselJ[1, x], BesselJ[2, x]}, {x, 0, 10}, PlotPoints -> 1*^5, 
    Filling -> {1 -> {2}}]
