How can I replicate this loop in cfscript (for use in cf10 / railo)

Question

I have this working nicely in tag format, but am trying to migrate everything into cfscript. How can I do this one? (essentially, it loops over from date1 to date2, and needs to be in 15 minute intervals.

<cfset from=now()>
<cfset to=dateadd("d", 1, from)>
<cfloop from="#from#" to="#to#" index="i" step="#CreateTimeSpan(0,0,15,0)#">
 ...stuff...
<cfloop>

It's how to specify the step bit which is getting me..

Answer 1

<cfscript>
  variables.dtNow = now();
  variables.dtTmrw = dateAdd('d',1,variables.dtNow);

  do {
    variables.dtNow = dateAdd('n',15,variables.dtNow);
    writeOutput(variables.dtNow);
  } while(variables.dtNow neq variables.dtTmrw);
</cfscript>
