regulating the time?

I agree with wirecutter you need to give more info. However if you are talking about a pendulum clock then you need to raise the pendulum up to make the clock run faster, This is done by a screw at the bottom of the pendulum in many cases but there are many different methods of raising the pendulum.

just keep regulating by adding one second for every second that goes by, happy regulating
