I would like it to "stamp" a date and time with a column entry for each row; ie, date/time stamp each time I enter a gross (or tare) weight or each time I enter an odometer reading.  Or when you simply click ENTER or push a programmable button.  I would like this for pocket excel on an Ipaq.

I agree regarding the time needed to enter the actual date and time; why spend the time to look up the information when the computer could record it with a keystroke?  Time is money -  unless it is time not watching where you are driving.
