We live in a 4 dimensional world
height, width, depth and time
when you want to meet up with someone you pick a place and a time.
measuring time is what humans created to coordinated in our 4 dimensional space.
We use our orbit around the sun and our spinning on the axis to create the 24 hours and 365 days everyone uses.

A machine has no sleep cycle that goes with the sun, instead can do millions of operations in a fraction of a second.
Which is why time lengths of hours, days, weeks, months are very VERY long for a computer. Computers can calculate so much in such little amount of time that it is believed that by 2050 a $1,000 computer will be more capable than the entire human race today...

We are quickly moving into this computer era and a lot of people are fearful for what can happen when technologies acceleration gets too fast.
