[TYPO3-english] Publish date: date and time

[Gregory Loichot]

Hello,

I'm running a TYPO3 4.5.x and I need a special feature: being able to 
specify time of a publish date. I know TYPO3 4.6 allows that natively 
but what about 4.5.x? Is there an extension able to do that (cannot find 
one) ? Other suggestions ?

Thank you for your answer.
Greg
