This appears to be an issue with data corruption over the serial port. I've modified the Processing UI so that it will discard samples when it sees a corrupted timestamp. We'll need to have a deeper conversation about data integrity sometime soon. With the Arduino's horsepower, there will be trade-off between ensuring integrity and speed.

I'm going to ask Jones Boys' Rocketry to test this change to make sure it's fixed before I close this issue.
