[TYPO3] lastUpdate problem

[Christoph Neuroth]

Hi,

I'm trying to implement a "last updated" label as explained in [1]. The 
problem is, in my ObjectBrowser I don't even have styles.content.lastUpdate - 
and if I set it, it does not produce anything :/
Is the tutorial referring to an old T3 Version or something? I use Typo3 
4.0b1. What's the most elegant solution to implement "last update" in recent 
T3 versions?

regards, Chris
