# Octave, <s>46</s> <s>43</s> <s>36</s> <s>30</s> 23 bytes

    tic;(-1e3:1e3)',toc*1e3

This will print:

    ans =
    
      -1000
       -999
       -998
       -997
       -996
       -995

If you don't like the `ans = `, then we have to add an additional 6 bytes for `disp`:

    tic;disp((-1e3:1e3)'),toc*1e3

Saved a lot of bytes thanks to a few reminders from rahnema1.

**Explanation:**

    tic;                              % Starts timer
             (-1e3:1e3)'              % A vertical vector -1000 ... 1000
        disp((-1e3:1e3)'),            % Display this vector
                          toc*1e3     % Stop the timer and output the time in milliseconds
