Hello

This uses the following formats.

app/assets/javascripts/discourse/app/lib/formatter.js

fa92f8bc9


      
          export function longDateNoYear(dt) {
            if (!dt) {
              return;
            }
          
            if (new Date().getFullYear() !== dt.getFullYear()) {
              return moment(dt).format(I18n.t("dates.long_date_with_year"));
            } else {
              return moment(dt).format(I18n.t("dates.long_date_without_year"));
            }
          }

You can change it in /admin/customize/site_texts

Search these two strings.

dates.long_date_with_year
dates.long_date_without_year

dates.long_date_with_year

Default
MMM D, YYYY LT

Change it to
MMM D, YYYY LTS

dates.long_date_without_year

Default
MMM D, LT

Change it to
MMM D, LTS

Note: This will change everywhere on your site where this date format used.
