Node Js Timestamp of a deletet task - date

Question

I have the following code. I want to display here the timestamp of the deleted task in my index.ejs file.
<% for(var i = 0; i < complete.length; i++){ %>
<li><%= complete[i] %> </li>
<% } %>
in my index.js i installed npm date-format liabrary and i have this code. But i don't get the code running with the deleted time in my ejs file
var format = require('date-format');
//console.log(format(new Date(), 'yyyyMMdd\tHH:mm:ss'));
var date_time = new Date();
console.log(date_time);
var task = [];
var complete = [];
//post route for adding new task
app.post("/addtask", function(req, res) {
var newTask = req.body.newtask;
//add the new task from the post route
task.push(newTask);
res.redirect("/");
});
app.post("/removetask", function(req, res) {
var completeTask = req.body.check;
//check for the "typeof" the different completed task, then add into the complete task
if (typeof completeTask === "string") {
complete.push(completeTask);
//check if the completed task already exits in the task when checked, then remove it
task.splice(task.indexOf(completeTask), 1);
} else if (typeof completeTask === "object") {
for (var i = 0; i < completeTask.length; i++) {
complete.push(completeTask[i]);
task.splice(task.indexOf(completeTask[i]), 1);
}
}
res.redirect("/");
});
i tried to use the date object and to display it with concatination, but it didn't work

I solved my own question. I installed moment and added to index.js
var moment = require('moment');
app.locals.moment = require('moment');
and then i added to my index.ejs file the code.
<% for(var i = 0; i < complete.length; i++){ %>
<li><%= complete[i] %> erledigt am <%= moment().format('DD.MM.YYYY, HH:mm:ss') %></li>
<% } %>
