A few minutes ago a user in the ColdFusion IRC channel asked about an ActionScript relative time script. What is a relative time script? It translates something like "December 10" to "8 days ago". Turns out Google found a bunch of examples here. I took the first example, a JavaScript one, and rewrote it. This version is ColdFusion 8 only since it uses <, but you could change that in about 2 nanoseconds for a cf7 and earlier version. I'll add this up to CFLib a bit later probably.
1<cfscript>
2function relativeTime(pastdate) {
3 var delta = dateDiff("s", pastDate, now());
4
5 if(delta < 60) {
6 return "less than a minute ago";
7 } else if(delta < 120) {
8 return "about a minute ago";
9 } else if(delta < (45*60)) {
10 return round(delta/60) & " minutes ago";
11 } else if(delta < (90*60)) {
12 return "about an hour ago";
13 } else if(delta < (24*60*60)) {
14 return round(delta/3600) & " hours ago";
15 } else if(delta < (48*60*60)) {
16 return "1 day ago";
17 } else {
18 return round(delta/86400) & " days ago";
19 }
20}
21</cfscript>

24<cfset pastdate = dateAdd("n", -9400, now())>
25<cfoutput>Paris had dignity #relativeTime(pastdate)#</cfoutput>

I'll update the wiki too (got to represent the ColdFusion!)
However, I'm concerned that your example is redundant. Not sure Ms Hilton ever had dignity! :)
For the sake of one character, best to change all "<" to "LT" so it works in everything.
