test.d:

------
module test;

void main()
{
    assert(0);
}
------

timer.d (or use your favorite timer app):

------
module timer;

import std.stdio;
import std.process;
import std.datetime;

void main()
{
    auto sw1 = StopWatch(AutoStart.yes);

    system("dmd test.d");
    system("test");

    sw1.stop();
    writefln("%s msecs.", sw1.peek.msecs);
}
------

DMD 2.052:
$ dmd timer.d
$ timer
> 81 msecs.

DMD 2.053:
$ dmd timer.d
$ timer
> 4127 msecs.

This is using XP SP3.
