Thread: 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
