@Vishan, when we talk about the date changing, we're talking about this one right here.

This date updates whenever there's a major event (Order confirmed, Production scheduled, Built, Shipped, etc) but it also updates when there is a minor event (Ship boarded/departed, Ship landed, now possibly Rail loaded). When you get a VINView trace, you also get an event log and all these events are detailed. So VINView will always show you when these happen.
So we believe you can determine when your vehicle was boarded by checking for the status date changing
after the ship date. If your ship date at the top is 1/31, and your last update is also 1/31, then we think it hasn't boarded yet.
Note that we also have evidence that it's not real accurate. So it can be a few days off, but it is still indicative of an event occurring.
