Did you register this extension ? $twig->addExtension(new Twig_Extensions_Extension_Date()); – Bonfire

Answer 1

If you're using Symfony 2,

And want to use some of the native twig extension

You have to declare as service something like :

services:
    twig.extension.date:
       class: Twig_Extensions_Extension_Date
       tags:
            - { name: twig.extension }

Answer 2

At first you need:

composer require twig/extensions

Then you need to register Date extension:

$twig->addExtension(new Twig_Extensions_Extension_Date());

After that you could use time_diff filter. All in docs

" Then you need to register Date extension " ; Where ? – Temperance

Either as a service, or somewhere in Controllers, but first way is better. – Invocate

Answer 3

I suggest You to use the KnpTimeBundle

So you can simply compare with the current date:

{# Returns something like "3 minutes ago" #}
{{ time_diff(myEntity.getMyTimeField) }}

This compare with the another date:

{# Returns something like "3 minutes ago" #}
{{ time_diff(myEntity.getMyTimeField , to ) }}

The translation is enabled by default, simply review the translations files or add as you need.

I've set the locale as IT, but the translation isn't done. Any suggestion? – Hymanhymen

Using github.com/KnpLabs/KnpTimeBundle seems to be the best solution for today (symfony 5). No customization needed just run:composer require knplabs/knp-time-bundle and use it {{ date|ago }} – Shien

Thanks @marcin to confirm after five years that the solution is still valid :) – Perpetual

Answer 4

Did you add the date extension?

Add the following line before using this formatting:

$twig->addExtension(new Twig_Extensions_Extension_Date());

Answer 5

Just install the time bundle, and the |ago filter will automatically work.

composer req knplabs/knp-time-bundle

{{ post.created_at|ago }}

The more modern way is to use stimulus https://www.stimulus-components.com/docs/stimulus-timeago

Then the time shown is accurate, even for a static page (e.g. a SPA).
