How to know the exact time

I want to know the exact time, and I'm looking for a time that's the standard when I set up a computer clock.

How is the time to check the most accurate?

pu1. Personally, a simple way to check is a cell phone! It's not a perfect fit and there's a slight error.

pu2. The computer will synchronize its time from Windows to the Internet Although there is a slight difference.
