Time & Date data verification/auto update

[Buschor]

I would like to see some auto updating of fields when dates and times (OUT IN, TAKEOFF LAND) are entered. For example, when I change the OUT date to a future day, the IN date should automatically change to the same future date (for we can't land in the past). The same goes for the OUT time. As a minimum, when the OUT time is changed, the IN time should automatically change to the same time. Same behavior should go for the TAKEOFF LAND fields.

I am one of those rare guys that log all 4 times giving me maxium flexibility for reports.
