ABSTRACT:
A system for automatically synchronizing, isolated clocks is disclosed. In the preferred embodiment, the internal clock of an automated external defibrillator (AED) or an external defibrillator (ED) is integrated with a radio broadcast to receive standard time. The system may also include a mechanism for synchronizing the clock or a computer tracking the time of emergency calls such as 911. Further, the system enables synchronization between the AED or ED internal clock and the 911 clock such that response times can be accurately determined.
