Direction of time

Does time have a direction? We treat it as though it is linear, irreversible and infinate. Yet, the shape of the skies repeats each day, as do seasons and the visibility of faraway stars. So how linear is time exactly? I find that the saying "history repeats" is remarkably true. What seems to change with different societies is how they get along with one another and what about themselves they value most. Not so long ago - about 60 years ago - we didn't seem to get along too well and decided that we all needed our space/borders. A little later - and still common today - we seem to want to understand each other more but continue to need our space and are willing to protect our capital. How does this compare to our behavior, say, 1000 or even 5000 years ago?
