 * I have new status posts on a WordPress blog that get published on Saturday nights
   with the title “UNCHECKED”.
 * There are a few dozen “client” WP sites that would like to display the current
   status from the blog infrequently from Saturday night until Friday at noon when
   the status may change to “DOWN”, “UP” or remain “UNCHECKED”.
 * Is there a way to configure wp_feed_cache_transient_lifetime to force the websites
   to display the current status using the following intervals?
 * Friday 8pm-9am: 3hr intervals for 157 hours
    Friday 9am-noon: 1hr intervals Friday
   noon-3pm: 15 minute intervals Friday 3pm-8pm: 5 minute intervals

 * You use the ‘wp_feed_cache_transient_lifetime’ filter by adding a filter callback
   with `add_filter()`. Your callback returns the value (in seconds) to use when
   setting the cache lifetime. Your callback could use a switch/case structure to
   determine which interval to return. The PHP `date()` function can be used to 
   get the current hour of day or even the day number.
 * I don’t know if this would force sites to use the current status though. The 
   filter fires when a `WP_Feed_Cache_Transient` object is created. I don’t know
   when that actually happens. It’d be worth a try to hook the filter as a simple
   proof of concept to see if changing the intervals (regardless of time of day)
   has the desired effect. If that checks out, then you can work on the switch/case
   logic.
