I didn't think about this initially, but now that you mentioned it, yes, two
computers with pefectly synchronized clocks would not sample the same
1-second periods if one started 0.5 seconds after another. That's because
the line
scheduler.scheduleAtFixedRate(new SnapshotHandler(), 0, 1,
TimeUnit.SECONDS);
in StrategyRunner.java starts the time immediately. This should be easy to
fix by changing the second parameter, which is "initialDelay", to the value
which would start the timer "on the second":
long initialDelay = 1000 - System.currentTimeMillis() % 1000;
scheduler.scheduleAtFixedRate(new SnapshotHandler(), initialDelay,
1000, TimeUnit.MILLISECONDS);
Can you make that code adjustments for tomorrow's test?
