About timestamp
Hello everyone,
I need to record a set of data items. For each data item, users may modify to some new content. So, I plan to use a timestamp field for each data item to record the time when user modifies data item last time. I am not sure whether I should use a simple integer value (like version information, which increase 1 each time when user modifies data item)? Which approach is better? What are the advantages and disadvantages of each approach? thanks in advance, George

Using a timestamp has the advantage that you can see when an item was changed (d'uh
 ), and enables you to see if several things were changed at the same time.
