Time and Frequency Division
The Time and Frequency Division, part of the NIST Physics Laboratory, maintains the standard for frequency and time interval for the United States, provides official time to the United States, and carries out a broad program of research and service activities in time and frequency metrology. *Note:  NIST Demonstrates Miniature Atomic Clock NIST researchers have demonstrated a minuscule atomic clock with inner workings about the size of a grain of rice and potential applications in atomically precise timekeeping in portable, battery-powered devices for secure wireless communications, more precise navigation, and other applications.
