jquery - Spring fmt tags + handlebars.js template + ajax -

i using springs fmt tags display date comment have being posted. this:

<fmt:formatdate type="both" value="${comment.date}" /> 

this works great comments have been posted. (written on page load)

the problem when dynamically adding new comment ajax.

then i'm using handlebars template follows.

<script id="new-comment-template" type="text/x-handlebars-template">     <div class="discussion-comment" id="{{id}}">         <h4 class="inline">             <small>                 <a href="/users/{{userid}}" class="text-primary inline">{{name}}</a> @ {{university}} {{date}}             </small>         </h4>         <form id="command" class="pull-right inline" action="/courses/${course.id}/${course.name}/comment/{{id}}"               method="post"><input type="hidden" name="_method" value="delete">             <button type="submit" class="btn btn-danger btn-sm">                 <i class="fa fa-trash-o fa-lg"></i>             </button>         </form>         <p>{{{message}}}</p>     </div> </script> 

but {{date}} variable comes server on wrong form , if i'm trying

<fmt:formatdate type="both" value="{{date}}" /> 

im getting error since value not exist when template being parsed (i guess).

i use springs fmt:formatdate tag since handles internationalisation.

is possible somehow?

if not i'm thinking of alternatives:

1. keep track of time on client. updating constantly, writing "5min ago", "10min ago" , on. until page refreshed.
2. try send time in right format server directly. possible run fmt:formatdate on server side?

thank you suggestions.
