About Atomic Clocks

I'm late, I'm late for a very important date! As much as they giggle at the exasperated and chronically late White Rabbit, punctuality is important to a lot of people, which is why an atomic clock is so helpful. Originally invented in 1949, the atomic clock is not a physical entity so much as standard of measurement. In this case, it measures time, which is transmitted via micro, optical, or ultraviolet frequencies using the principles of atomic physics. Considered to be the most accurate timekeeping tool available, individuals can purchase a digital atomic clock or an atomic wall clock for their personal use. These devices receive the same electromagnetic frequency used to determine the standards for international time, set television frequencies, and operate GPS units for the military. In addition to offering several different types of new atomic clocks, eBay sellers also offer used and refurbished units designed to make this accurate timekeeping tool accessible to everyone at a great price.
