The More Accurate Way To Tell Time

I wanted to talk to you about a more accurate way to tell time. There used to be a real problem with clocks at one time. You've probably noticed that over time your clock either gets faster and slower. This can be most apparent with your alarm clock. Sometimes you'll want up during the news. Other times you'll wake up when music is playing. It's not that the clock at the radio has got fast or slow, it's your clock that is changing. The reason is that your clock really isn't that accurate, even if you have a digital one. I'm going to explain why and show you the better choice.

The problem with a lot of clocks is the ability to estimate a second. There are a lot of different ways that this is figured out and varies between clocks, but I'll explain why a simple digital clock will get faster or slower over time. Basically it measures the power coming out of the wall. Electricity will come in your house at a 60Hz wave (or a wave every 1/60 seconds). The issue is that the wave can very in speed. Usually in the middle of the night it can go down to 59Hz or 61Hz. If you live down a back street you can experience wild variations in your time.

The accurate way of telling time is with an atomic cock. This one uses the natural vibrations of atoms to tell the time. Since atoms are a lot more consistent than electricity frequencies, you can get a very accurate time calculation at all times. This is the type of clock that they'll use at a radio station and television station.
