The way that logic reads, the Application.TimeStamp will always be "less
than" 20 the first time the application is loaded--so your CFHTTP tag will
never run.
Change the code to something like:
<cfif
not structKeyExists(Application, "TimeStamp")
or
(dateDiff("n", Application.TimeStamp, now()) gt 20)>
<cfset Application.TimeStamp = now() />
<cfhttp
url="http://feeds.bbc.co.uk/weather/feeds/rss/5day/id/3314.xml";
method="GET" resolveurl="No"></cfhttp>
<cfset Application.weather_xml = xmlParse(cfhttp.FileContent) />
</cfif>
There's no need to convert your Application.TimeStamp variable to any
specific formatting--you can just set it to now().
