Abstract:
The claimed method and system monitors computer system timer(s) relative to other timers to detect discrepancies and/or may capture an offset to provide a method of more accurately determining a current time. The invention may also provide a method to detect power source tampering using a last known good time and may provide a means to securely initialize system time using an encrypted time stamp.
