moment js gets current time but not the created time - angularjs

Question

I'm trying to retrieve the created_at time
but instead it renders the current time. which is not what i want.
I'm using laravel 5.5 in conjunction with moment.js
<p> <% post.created_at | phpDate : "human" %></p>
main.js
app.filter('phpDate', function() {
// A filter declaration should return an anonymous function.
// The first argument is the input passed to the filter
// Any additional arguments are paramaters passed AFTER the filter name
return function(input, format) {
// Create an instance of Moment. Use both the
// date value and timezone information PHP sent
var date = moment.tz(input.date, input.timezone);
if (format == "human") {
// Special case for formatting. If user asks for "human" format
// return a value like "13 minutes ago" or "2 weeks ago" etc.
return moment().subtract(1, 'days').calendar();
} else {
// Covert the moment to a string using the passed format
// If nothing is passed, uses default JavaScript date format
return moment().format('lll');
}
};
});

with the help of a highly respectable user on this site we were able to fix it, just needed add input within moment parathesis.
app.filter('phpDate', function() {
return function(input, format) {
if (format == "human") {
// add input then it works
return moment(input).subtract(1, 'days').calendar();
} else {
return moment().format('lll');
}
};
});
