ATS uses your language's DATE_FORMAT_LC5
date format. This is the standard date and time format Joomla! uses in all listings of items.
BTW, this is not the US format. The US date format is mm/dd/yyyy. Also, there is no single European date format. For example, both Cyprus and England unsurprisingly share the same date format of dd/mm/yyyy. If you go to Germany, however, the format is dd.mm.yyyy (dots, not forward slashes). This is exactly why Joomla! has the DATE_FORMAT_*
constants in each language file. Translators are supposed to change them to what is appropriate for each locale. English (United States) needs different date formats than English (United Kingdom).
