[vhdl-200x-ft] to_string (time, resolution) problem

I was playing around with the to_string function:

   function to_string (
     VALUE : in TIME;
     JUSTIFIED : in SIDE := right;
     FIELD : in WIDTH := 0;
     resolution : in TIME := Sim_Resolution
     ) return STRING;

and looking into implementations.

In the LRM, there is only one way to get "time" into any other format:
function "/" (anonymous, anonymous: TIME) return universal_integer;

Since 1 hr / 1 fs > integer'high there is no way I can do this,
because I need to use "real" math to manipulate the number.

Can I recommend that we drop this one and go back to:
   function to_string (
     VALUE : in TIME;
     JUSTIFIED : in SIDE := right;
     FIELD : in WIDTH := 0
     ) return STRING;

Though I like the idea of the deferred constant "sim_resolution".
It gives you something to check in your testbenches to make sure
that you have the correct simulation resolution set.

If somebody comes up with a clever idea, we can always revisit it
later.
