What I did is create a table in the design view, created a column with the name "Training_date" and the Default value "Date()".
If the table's default value is Date() and I'm adding a record today, I'm probably happy with the date I see so I'll leave it alone. If I look at that record tomorrow, it will be a different date because there is a function in the field, not a value. Perhaps that is what is happening.
The more we hear silence, the more we begin to think about our value in this universe.
