Freemarker "date" to Unix timestamp?

Question

Hi ya'll!&nbsp;I'm attempting to implement a snippet of Javascript code within my community's page wrapper; the snippet requires the user's registration date in 10-digit-timestamp form.&nbsp;I'm able to get&nbsp;user.registrationTime via Freemarker, but this is a string formatted like: "April 9, 2018 12:19:18 PM". Does anyone know how to convert this to a seconds-since-Epoch timestamp? I've searched Google / the Freemarker documentation but haven't found the info I need.&nbsp;Thanks!- Caroline&nbsp;

CarolineSFirst, you need to convert it to date format then ?long will work. See here&nbsp;https://prnt.sc/j371fr&nbsp;${datesupport.parseAsIso8601(user.registration_time)?long}&nbsp;&nbsp;&nbsp;

According to this documentation, you should be able to use the ?long builtin against the backing date to get the epoch date:  https://freemarker.apache.org/docs/versions_2_3_17.html

Thank you,&nbsp;DolanH!&nbsp;Unfortunately, this isn't working for me, as the ?long only works on a number, and the date I'm working with appears to just be a string.&nbsp;&nbsp;Here's the error, in case you're curious:For "?long" left-hand operand: Expected a number, but this has evaluated to a string (wrapper: f.t.SimpleScalar): ==&gt; user.registrationTime [in template "Hitbox" at line 6, column 53]I'll keep working on this!

Thank you very much,&nbsp;VikasB! I hadn't found the datesupport library in my searches - how very helpful!&nbsp;Unfortunately, though, I can't get it to work.${datesupport.parseAsIso8601(user.registrationTime)}gives me&nbsp;&lt;div style="font-style: italic; font-weight: lighter; color: darkGrey; background-color: Beige; padding: 10px;" class="lia-widget-not-found"&gt;
	This widget could not be displayed.
&lt;/div&gt;Note that${user.registrationTime}DOES work to give me the user's registration time (sample result:&nbsp;Tue Mar 20 14:31:45 PDT 2018)&nbsp;Do I need to do something special to enable datesupport?&nbsp;Thanks!

Ok, so user.registrationTime gives me a string formatted like this: "Wed Jun 14 15:37:14 PDT 2017" - which is not ISO format (example&nbsp;ISO format: 2017-06-14T15:37:14-07:00).&nbsp;How can I turn the string that user.registrationTime gives me into ISO format (or just directly into milliseconds since the epoch...)
