[TYPO3-english] Compare dates on TS

[Sergio Catalá Gil]

Thanks, Dmitry, for your answer. I used userFunc as it is explained in
the TSRef and it works for a string parameter. What I would like to use
now is a certain field from the actual tt_news record, but I don't know
how. 

Example:

[userFunc = user_compare_dates(plugin.tt_news.archivedate.value)]
	do some stuff...
[else]
	do other stuff...
[end]

It ignores my parameter. 

Thanks in advance, 
Sergio
