The pull of earth's gravity causes the motion on the downswing, while momentum keeps it going on the upswing.
From potential to kinetic and back again - with every swing.
Life is like a pendulum it swings back and fourth
As far as I know they have more to do with Newton's law that every action has a opposite and equal reaction. As far as them telling time it may have to do with the pendulum and how long each period (swing) is.
A pendulum whose period is precisely two seconds, one second for a swing forward and one second for a swing back, has a length of 0.994 m or 39.1 inches.
Using a pendulum as an example: a pendulum swings from left to right (first swing) and then swings back again right to left (second swing). A complete oscillation is composed of both swings.
Gravity makes a pendulum swing back and forth. The object starts at one point, and then moves in a circular motion to the apex of it's next point. The kinetic energy becomes less and less as time goes on if no extra energy is added.

it all has to do with a pendulum when you swing back and forth you are using potenial and kinetic enery

No, the swing of the pendulum will never carry it back quite as high as it was when it started. The pendulum must work against air resistance, and so a little bit of momentum is lost with every swing. Even if the pendulum operated in a vacuum, there would still be some tiny amount of friction at the point where the pendulum is attached to its frame. The swing of a pendulum is never 100% efficient. So the pendulum will run down.
A pendulum transfers potential gravitational energy (at the top of its swing) to kinetic energy (movement at the bottom of the swing) and then back again (at the top on the other side).
