You should use the -E version to Python, so that site-local settings (e.g.
PYTHONPATH) don't interfere in the measurement.
Here:

[2.7]
$ time -p cpython/release2.7-maint/python -E -c "print('hello world')"
hello world
real 0.01
user 0.01
sys 0.00
[3.2]
$ time -p py3k/py3k/python -E -c "print('hello world')"
hello world
real 0.02
user 0.02
sys 0.00
