It's even more interesting:  My version worked but it is slightly
different from your original in that Timing is enclosed in Main
procedure.  When I put Timing in separate package and it also worked
fine.

When I used your code exact it did show 0 time.  It got to do with
elaboration sequence as was mentioned already.  I think for practical
reasons real-time applications will be multi-package anyways, so I
would not worry about it much.
