[TYPO3] Anything like: global site's last update time?

[Cyprian Kowalczyk]

Could some experienced developer give me a hand with this one:
To get this site's last update time I could descent through the page tree  
and check all records from all pages.
I could use the same functions that Web > List uses, yet I don't know  
where to look for them.
Should I use class t3lib_admin (how)?

I could just query for 'tstamp' from some tables, but I think the first  
way is better, isn't it (f.e. each time some extension is added I'd need  
to reconfigure my query)?
