MySQL has a date type called timestamp which records the time of the last update of a row. Add such a field to your table. This field changes with every update, though. If you want to keep the insertion time, use a datetime field and a trigger which updates this field with the value now() after insertion.
gulbano there is no other way to track a record other than keeping log of it add a column in you table and insert the datetime of each record insertion and you will be able to keep the log of the future record insertions
