This is a known behaviour of TYPO3, as the cache doesn't at first relate 
to start/stop-dates for content elements. So the setting 
config.cache_clearAtMidnight=1 is useful exactly for that purpose, if 
you need "day-based" start/enddates.

If you need more precise control (e.g. hour-wise), you will need to 
setup TYPO3 to expire cache each hour globally 
(config.cache_period=3600) or you set it specifically for the pages 
where you need it (e.g. home-page). Ugly, but it's currently how it works.
