# Respect to What Time is Calculated in Space

This may be the silly and stupid question but I have read that time appears to move slower near massive objects because the object's gravitational force bends space-time and the phenomenon is called gravitational time dilation means time moves slower as gravity increases but I want to know how and with respect to what time is calculated at a different position of space do time is calculated wrt earth time or any other and also since times moves slower as gravity increases this means what

• Do our analog clock hand move slower there if so how since it depends on the mechanical property or it means ageing of the body

• Do it depends on the ageing of the body if so how since body ageing depends on the environment and natural things

I have searched this type of question on the Internet but I did not get a proper answer majority of answer are based on theories and formula but I was looking for an intuitive and rigorous answer

The intuitive and rigorous answer is highly appreciated
