Statmonitor subsecond sampling generates incorrect timestamps
In most cases, the timestamps that statmonitor collects from GemStone are rounded to the nearest whole number of seconds before being recorded. This allows them to be easily understood with the VSD display.
With sub-second timestamp intervals, however, the seconds field should be truncated, not rounded. This rounding resulted in timestamps that were incorrect by up to 1 second.
Since VSD skips out of order timestamps, the charts displayed by VSD did not include all samples.
