Auction plugin displays dates in English — how to localize to Ukrainian?

Hi everyone!

I’m using the Auction plugin for Osclass on a fully Ukrainian-language website. The system locale is set to Ukraine, and other plugins correctly display dates in Ukrainian (Cyrillic).
However, the Auction plugin always shows English date formats like:
Fri, 02 Aug or 02. Aug

So I have a few questions:
Why is the Auction plugin ignoring the system locale and displaying English date strings?
Is there a way to make the plugin display dates in Ukrainian — at least using Cyrillic month and day names?
Has anyone encountered this issue and found a solution or workaround?
Any help or advice would be really appreciated. Thank you in advance!

It depends (or should depend) on server localization.
You might customize format in plugin settings or manually in plugin files - date() function.

Thank you for your reply
I noticed that if I change the date format from 'D, d M' to 'd.m.Y' in the following function, it breaks the auction duration calculation.

// CALCULATE ESTIMATED DELIVERY
function act_estimated_delivery($days, $as_text = true) {
  $format = 'D, d M';
  return date($format, strtotime("+$days days"));
}
Can someone explain why this happens, and how I can safely localize the date (e.g. show Ukrainian or localized day/month names) without affecting the logic?

Is there a way to keep 'D, d M' for internal calculation and show a translated string only on the front-end?

Thanks in advance!

You can change
$format = 'D, d M';
into ie:
$format = 'Y-m-d';

You can change

Code: [Select]

$format = 'D, d M';
into ie:

Code: [Select]

$format = 'Y-m-d';

I changed it this way, but it seems that it affects the auction end time.

Format of date cannot change date calculations.
Do you have way to test this, example or demo or something?
