EpikTimer

EpikTimer is a programmer's stopwatch that is capable of measuring very short events with traceably high precision over long periods of time. It's simple to use, consumes virtually no CPU and requires only 25 bytes of ram to implement a timer instance. The component provides a single internal timer... but unlimited numbers can be declared externally and linked to a single EpikTimer component on the form.
