Or instead of creating a table and tying up one more mysql thread, just save the timestamp in a file. This could be as simple as that, you could use XML, you could use INI parser, you could use any number of things. Also, if the HEAP is created per "session", then just store that timestamp in a session variable and avoid any disk i/o that way.
