relative_time should render texts in local browser language

[BenPru]

relative_time render texts currently always in english.
Example: "{{ relative_time(states.sun.sun.last_changed) }}" --> "44 minutes" - Current Browser language: german.
So it should be "44 Minuten".

We get this from the backend, the backend currently doesn't know the user language.

Not sure about the Docker container question.

But in general: Instead of having the backend provide relative_time() it might be better to provide the isoformat() time string because then the frontend can localize the value rendering based on the set HA user language (there are different format options for the Lovelace config).

That's is e.g. what is happening with the internal times such as last-changed and last-updated. They provide an ISO datetime string and leave the formatting to the frontend.

Now it's possible to use state_translated to get the translated state.
Is it maybe also possible to provide a similar function for relative_time e.g. relative_time_translated ?

Any ideas on how to fix or mitigate this issue?

    {% macro humanize_time_ru(seconds) %}{% set minutes = (seconds / 60) |
    round(0, 'floor') %}{% set hours = (seconds / 3600) | round(0, 'floor') %}{%
    if seconds < 60 %}{{ seconds }} {{ 'секунд' if seconds % 10 != 1 or seconds
    == 11 else 'секунду' }}{% elif seconds < 3600 %}{{ minutes }} {{ 'минут' if
    minutes % 10 != 1 or minutes == 11 else 'минуту' }}{% else %}{{ hours }} {{
    'часов' if hours % 10 != 1 or hours == 11 else 'час' }}{% endif %}{%
    endmacro %}

I use this macro at the start of text field and this one to generate text itself

{{ humanize_time_ru(as_timestamp(now()) - as_timestamp(states.person.noado.last_updated)) }}

But it's language specific (RU). I've just used DeepSeek to generate it.
