[TYPO3-english] auto-clearing cache for displaying content released by timer

[Simon Child]

I use the access/start-time feature to release some content (including 
tt_news items) at specific times. But often they don't display until the 
cache is cleared, which means that I have to be around to clear the cache 
manually, which rather defeats the purpose of setting the start-time!

Is there a way within TYPO3 (4.7) to set the cache to clear daily at a 
specific time or times?

I've searched and found a cron job solution but it is for TYPO3 4.1

I think it needs updating for 4.7 - can anyone give me any pointers?

Thanks
