It's because you re-used the variable names startDate and endDate, so you
re-wrote the value of each variable to strip out the time and then asked
for the time. Always be sure to 'var' all variables in a function, and
you'll avoid the snafu. If you do the following, you'll even get a runtime
error letting you know the problem (cannot var a variable with the same
name as an argument):
<cffunction name="dateFormatter2" returntype="string" access="private"
output="No">
<cfargument name="startDate" type="date" required="Yes" />
<cfargument name="endDate" type="date" required="Yes" />
<cfscript>
var result = "";
var startDate = "";
var startTime = "";
var endDate = "";
var endTime = "";
startDate = dateFormat(arguments.startDate, "dd mmmm yyyy");
startTime = timeFormat(arguments.startDate, "HH:mm");
endDate = dateFormat(arguments.endDate, "dd mmmm yyyy");
endTime = timeFormat(arguments.endDate, "HH:mm");
</cfscript>
<cfsavecontent variable="result">
<cfoutput>
Start: #startDate#, #startTime#
<br />End: #endDate#, #endTime#
</cfoutput>
</cfsavecontent>
<cfreturn result />
</cffunction>
<cfoutput>
#dateFormatter2(now(), now())#
</cfoutput>
Use different var names, and it works fine:
<cffunction name="dateFormatter2" returntype="string" access="private"
output="No">
<cfargument name="startDate" type="date" required="Yes" />
<cfargument name="endDate" type="date" required="Yes" />
<cfscript>
var result = "";
var start = "";
var startTime = "";
var end = "";
var endTime = "";
start = dateFormat(arguments.startDate, "dd mmmm yyyy");
startTime = timeFormat(arguments.startDate, "HH:mm");
end = dateFormat(arguments.endDate, "dd mmmm yyyy");
endTime = timeFormat(arguments.endDate, "HH:mm");
</cfscript>
<cfsavecontent variable="result">
<cfoutput>
Start: #start#, #startTime#
<br />End: #end#, #endTime#
</cfoutput>
</cfsavecontent>
<cfreturn result />
</cffunction>
<cfoutput>
#dateFormatter2(now(), now())#
</cfoutput>

Subject: Passing a Date Time Value to a function
It's been one of those days already - can anyone tell me why the time gets
stripped out? I'm aware that I'm using 'date' as an argument type, but
datetime throws an error and there's nothing in CF8 docs on it... How do I
preserve the time data?
<cffunction name="dateFormatter2" returntype="string">
<cfargument name="startDate" type="date">
<cfargument name="endDate" type="date">
<cfscript>
var result ="";
startDate=dateFormat(arguments.startdate, 'dd mmmm yyyy');
startTime=timeFormat(arguments.startdate, "HH:MM");
endDate=dateFormat(arguments.enddate, 'dd mmmm yyyy');
endTime=timeFormat(arguments.enddate, "HH:MM");
</cfscript>
<cfsavecontent variable="result">
<cfoutput>Start: #startDate#, #startTime# <br />End: #endDate#,
#endTime#</cfoutput>
</cfsavecontent>
<cfreturn result>
</cffunction>
<cfoutput>
#dateFormatter2(now(),now())#
</cfoutput>
Cheers!
