We have the black box and Version 3.0 sortware. The date and time are accurate on the monitor. If i dont back it up, I get everything with the date 7_26_1996 and enters into the software with the crop year 1996, as you would expect. However, if you come back to the same field the next day, put the card in and erase the previous days data, it says the card needs formatting and does that. It will then log correctly. If you have any ideas why it is doing this, I am all ears. I have no earthly idea. I think this software is about the most unforgiving of "mistakes" of anything I have ever used.
