here is what i came up with.
may have been an adaption of someone elses
something, but its what i use
<cfcomponent displayName="isDateInDayLightSavingsTime" hint="The hint
is in the question I say!">
<cffunction name="isDateDST" access="public" output="1"
returntype="any">
<cfargument name="dateFeed" type="date" required="Yes"/>
<cfset startDate =
"04/01/#dateFormat(arguments.dateFeed,'yyyy')#">
<cfset endDate =
"11/01/#dateFormat(arguments.dateFeed,'yyyy')#">
<cfif NOT (dayOfWeek(startDate) eq 1)>
<cfset targetDOW = 8 - dayOfWeek(startDate)>
<cfelse>
<cfset targetDOW = dayOfWeek(startDate)>
</cfif>
<cfset beginDST = dateAdd('d',targetDow,startDate)>
<cfif NOT (dayOfWeek(endDate) eq 1)>
<cfset targetDOW = 1 - dayOfWeek(endDate)>
<cfelse>
<cfset targetDOW = dayOfWeek(endDate)>
</cfif>
<cfset endDST = dateAdd('d',targetDow,endDate)>
<cfif (dateDiff('d',beginDST,arguments.dateFeed) GTE 0)
and
(dateDiff('d',endDST,arguments.dateFeed) LT 0)>
<cfset withinDST = 1>
<cfelse>
<cfset withinDST = 0>
</cfif>
<cfreturn withinDST/>
</cffunction>
</cfcomponent>
