ABSTRACT:
A system for automatically correcting data of recorded times from a plurality isolated clocks is disclosed. In the preferred embodiment a computer implemented software is used to download recorded time data from an automatic external defibrillator (AED). The computer also includes an internal clock synchronized with a 911 emergency call time tracking clock. On the initiation of the download, the computer compares its internal clock with the clock on the AED and calculates a correction or adjustment factor. Recorded event data, representing AED intervention times, are downloaded from the AED's memory bank and the software computes a corrected response time using the calculated adjustment factor. This corrected response time is then stored in the AED.
