Marathon Large Digit Radio Atomic Clock with Six Time Zones

No need to worry about this clock running fast or slow — radio signal from the National Institute of Standards and Technology (NIST) in Colorado ensures precise time. Select from six time zones: PST (Pacific Standard Time), MST (Mountain Standard Time), CST (Central Standard Time), EST (Eastern Standard Time), AST (Atlantic Standard Time), and NST (Newfoundland Standard Time). Outside these time zones, the clock can be set manually. Set clock to display in 12- or 24-hour format. Features include a built-in stand for tabletop display or a keyhole slot for wall mounting; temperature display in °F or °C; and calendar display of month, date, and day of week.
