Radio frequency clocked device

A clock system, comprising:

• an RF clocked device comprising
• a signal processor operable to receive an external RF signal having an RF signal frequency and output a clock signal having a clock frequency based on the RF signal frequency,
• a clock operable to receive, and operate, using the clock signal, the clock outputting at least one of a time and a date, wherein the clock is operable to receive reference timing information provided by a time standard for synchronizing the clock with the time standard, and
• a backup clock operable to provide at least one of an initial time and date to the clock upon startup of the RF clocked device in the absence of timing information from the time standard;
• and
• a client device operable to receive timing information from the RF clocked device.

A method for timing a clock, comprising:

• receiving at least one of an initial time and date from a backup clock upon startup of an RF clocked device in the absence of timing information from a time standard;
• receiving an external RF signal having an RF signal frequency;
• processing the RF signal and outputting a clock signal having a clock frequency based on the RF signal frequency;
• providing the clock signal to a clock;
• and
• operating the clock using the clock signal, the clock outputting at least one of a time and a date.
