3. 7 includes/cron.inc \_signup_cron_autoclose()

Helper function that handles auto-closing time-based nodes during cron.

Loops over all the node types that are signup-enabled. For each one, it invokes the method for the installed event/date backend module to get the right query fragments, and builds a query to find all nodes of that type where signups should be closed (e.g. events that already started, etc).
