#Octave, 46 43 36 30 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

If you don't like the ans = , then we have to add an additional 7 bytes for disp:
