use of org.eclipse.tracecompass.tmf.core.markers.TimeReference in project tracecompass by tracecompass.

the class PeriodicAnnotationProvider method adjustReference.

     * errors in floating point calculations with large numbers.

             * multiple of den and calculate index * period = (index * int) +
