Обсуждение: Internal time stamps?
Does postgresql have any kind of internal time stamps for a table entry? I can create a field that is 'timestamp' and store it there, I was just wondering if it was already done internally. I'd hate to duplicate something it already does. :-)
If it does store it internally, how do you access it?
Thanks!!

If you want to store a timestamp of when a row was inserted, just use a TIMESTAMP type column (with- or without- time zone; WITH TIME ZONE is recommended) and insert CURRENT_TIMESTAMP or NOW or whatever function you wanna use.
