How can I tell when a MySQL table was last updated?

Question

In the footer of my page, I would like to add something like \"last updated the xx/xx/200x\" with this date being the last time a certain mySQL table has been updated.

Answer 1

I would create a trigger that catches all updates/inserts/deletes and write timestamp in custom table, something like tablename | timestamp

Just because I don't like the idea to read internal system tables of db server directly
