Nuclear Clock

From the developer:" Nuclear Clock keeps your computer's clock running on the correct time. It downloads the time from a NIST (National Institute for Standards and Technology) Time server, which is connected to a highly accurate atomic clock. Nuclear Clock is great for correcting faulty system clocks, and does not require user input. Easy to use and already configured, this program has many options including automatic time synchronizations and a pleasant display that makes it easy to synchronize watches."
