More Information

This tag works just like the_modified_time(), which also displays the time/date a post was last modified. This tag must be used within The Loop. If no format parameter is specified, the Default date format (please note that says Date format) setting from Administration > Settings > General is used for the display format.

If the post or page is not yet modified, the modified date is the same as the creation date.

Use get_the_modified_date() to retrieve the value.
