Is it possible to change X Hours Ago to date in WP Admin?

On the WooCommerce Orders admin page, the order date column is set on line 256 of this file:

../wp-content/plugins/woocommerce/includes/admin/list-tables/class-wc-admin-list-table-orders.php

If you want to change “ago” you can translate it. If you want to change the human readable time (e.g. “10 hours”), you can override the WordPress human_time_diff function. This answer has more details.
