回答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 }

回答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

回答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

Did you add the date extension?

Add the following line before using this formatting:

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