Output

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

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.

Hope this help

Answer 4

Did you add the date extension?

Add the following line before using this formatting:

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