How to translate timestamp?

Question

This script comes with the theme I purchased that output "Published 3 days ago on Feb 21, 2019" on the article. However I couldn't get the "%s ago" translated, which includes variables of minute(s), hour(s), day(s), etc. What is the best way to translate just these variables?

<?php esc_html_e( 'Published', 'enews' ); ?>
<?php printf(esc_html__( '%s ago', 'enews' ), human_time_diff( get_the_time( 'U' ), current_time( 'timestamp' ) ) );?> 
<?php esc_html_e( 'on', 'enews' ); ?><time itemprop="datePublished" datetime="<?php the_time('Y-m-d'); ?>">
<?php the_time(get_option('date_format')); ?></time>

Answer 1

The "%s" will be replaced by strings translated in the WordPress Core "default" text domain. e.g. "%s mins", "%s hours", etc..

Find these in your core translation files and translate them too.
