/**
* Check for updates if the configured check interval has already elapsed.
* Will use a shorter check interval on certain admin pages like "Dashboard -> Updates" or when doing cron.
*
* You can override the default behaviour by using the "puc_check_now-$slug" filter.
* The filter callback will be passed three parameters:
* - Current decision. TRUE = check updates now, FALSE = don't check now.
* - Last check time as a Unix timestamp.
* - Configured check period in hours.
* Return TRUE to check for updates immediately, or FALSE to cancel.
*
* This method is declared public because it's a hook callback. Calling it directly is not recommended.
