I expect that passes only because old_date was basically set to
Time.now (so has a fractional second component), whereas
team.reload.updated_at is fetched from the database, so the fractional
portion of the second is lost.
In rails 2.1 game.team.save is a no-op because only changed attributes
are saved (and here none are changed). You can force a save by
modifying any attribute or calling one of the _will_change! methods ie
def touch
updated_at_will_change!
save
