**The Axis Of Rotation** And Some Of Her Mass, Reducing Her **Moment Of Inertia**. Since **Angular Momentum** Is Conserved, Her **Rotational Velocity** Must Increase To compensate And When She Takes Her Arms Outward She Gets Gradually Slower.

Now-a-days, Due To Development As The Height Of The Buildings is Increasing. **The Distance Between The Tower And The Center Of The Earth Increases And Thus The Moment Of Inertia Increases And The Angular Velocity Decreases**.
As The Angular Velocity Is Decreasing Gradually It Is Taking More Time To Complete One Rotation In One Day. Which Can Cause The Time To Get Slower Or The Day To Get Longer.

**So, Is The Earth Getting Slower Or The Day Getting Longer...!!??**

Discounting vanishingly tiny relativistic effects, if the earth is spinning more slowly, then the days are getting longer. As a matter of fact, this effect has already been measured after massive tectonic events such as the earthquake in the Indian Ocean in 2004. That does not mean, however, that "time is running more slowly".

General relativity does predict (and has been confirmed by Gravity Probe B experiments) frame dragging by rotating bodies, but such effects are extraordinarily difficult to even detect and measure. You're suggesting changes in time dilation due to the already very tiny

Even if there is such effect it should be negligible

But On The Earth And Building Point Of View, The Effect shouldn't be negligible, I guess!!
