The pendulum is not a reliable time standard mostly because of friction and gravity. To be a reliable time standard, a pendulum would need to form a continuous arc that did not deviate over time. Gravity is always trying to get the pendulum to stop and friction causes the pendulum's fulcrum to resit continued movement. Eventually, a pendulum will stop moving and remain stationary unless acted upon by an external force.

What is the pendulum used for?
the pendulum is used to tell time
Why does a pendulum lose time in summer and gain in winter?
Time period of pendulum is, T= 2π*SQRT(L/g) In summer due to high temperature value of 'l' increases which increases the time period of pendulum clock. Hence, pendulum clock loses time in summer. In winter due to low temperature value of 'l' decreases which decreases the time period of pendulum clock. Hence, pendulum clock gains time in winter.
What is the purpose of a pendulum in pendulum clocks?
The purpose of a pendulum in a pendulum clock is that it uses its weight as a way to keep accurate and precise time. When it swings back and forth the weight keeps it going at the same time every time making for more accurate timekeeping.
What is effect on time period of simple pendulum at centre of earth?
At the center of the Earth there would be no effective gravity; a pendulum wouldn't work as a pendulum.
What are the physical parameters in the investigation of a simple pendulum?
The physical parameters of a simple pendulum include (1) the length of the pendulum, (2) the mass of the pendulum bob, (3) the angular displacement through which the pendulum swings, and (4) the period of the pendulum (the time it takes for the pendulum to swing through one complete oscillation).
The advantage of pendulum standard for the measurement?
of time
Why you cannot take time period of simple pendulum as a standard time period?
Because length of the pendulum which is equal to distance between the point of suspension and g is the gravitational acceleration and a body repeats its to and fro motion in equal interval of time that's why we cant take standard time period.
What are the drawbacks to use the period of a pendulum as a time standard?
Friction with the air, friction with it's axle, motion of whatever it's mounted on, variations in gravity (due to geographic location, pull from the moon, etc.), entropy, and undoubtedly many many more factors all make the pendulum a mediocre time standard.

Would a pendulum on the moon make a poor standard for the unit of time?
It would work it if is calibrated to account for the lower gravity on the Moon.
How does the length of the pendulum effect the pendulum?
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
If pendulum is made to swing in water compare the time taken for this pendulum to come to a complete stop with the time taken by a pendulum swinging in air?
The pendulum will take more time in air to stop completely in comparision with water

What is second pendulum?
Second's pendulum is the one which has 2 second as its Time period.
Relationship between period of pendulum and length?
The longer a pendulum is, the more time it takes a pendulum takes to complete a period of time. If a clock is regulated by a pendulum and it runs fast, you can make it run slower by making the pendulum longer. Likewise, if the clock runs slow, you can make your clock run faster by making the pendulum shorter. (What a pendulum actually does is measure the ratio between time and gravity at a particular location, but that is beyond the scope of this answer.)
Can the time period of a pendulum be infinite?
Perhaps if either:The length of the pendulum is infiniteThe pendulum is in perfect zero gravity and has no momentumBut in each of those cases, does it really qualify as a pendulum?
