It troubles me that no one has had an answer to this so far.
I tried asking roughly the same question of the velocity-users list and
was told that a new version of Velocity now does arithmetic with
non-integer numbers, but two things make that problematic: first, I
have limited access to the server to install software; second, I can't
believe that no one in all of XWiki's lifetime has ever tried to do any
date calculations, such as the difference of two dates, or
adding/subtracting intervals.
Isn't there an easier way to do this? All I want to do is decide
whether something's a week old.

It seems that a Velocity #set directive fails when the RHS involves any
arithmetic operation with long integers.
Specifically, I just wanted to determine the difference between two
dates, thus:
#set ($age = $xwiki.currentDate.time -
$obj.xWikiObject.getDateValue("donedate").time)
I confirmed that I got credible results from both of the operands by
printing them, and I could assign either of them to another variable
name, but setting $age to the result of any arithmetic operation with
any of them always gave "$age" as the formatted result.
This shouldn't be this hard, should it?

Hi Brian.
I am not sure about with Velocity but you should be able to do this
easily with a Groovy script.
It basically is Java without the braces and type declarations so it
is very powerful. Apologies if I have it wrong below but I have only
started playing with it a few days ago.
Try something like this below in your page.
<%
def today = new Date()
println today
if(testitem < (today - 7)
{
println "This is more than a week old"
}
else
{
println "This is less than a week old"
}
%>
If someone who knows Groovy well can correct that for you it might be
a solution.
Hope it helps.
Cheers,
Mark

Typical. I missed a brace off the if statement.
Sorry if you just cut and pasted the wrong answer.
Cheers,
