Displays the time at which the post was last modified.

$format string Optional

Format to use for retrieving the time the post was modified. Accepts 'G', 'U', or PHP date format.
Defaults to the 'time_format' option.

Default: ''

If you want to display both the modified time and the creation time, you may want to use an if statement to avoid showing the same time/date twice.
For example:

if ( get_the_modified_time() != get_the_time()) )

function the_modified_time( $format = '' ) {
	/**
	 * Filters the localized time a post was last modified, for display.
	 *
	 * @since 2.0.0
	 *
	 * @param string|false $get_the_modified_time The formatted time or false if no post is found.
	 * @param string       $format                Format to use for retrieving the time the post
	 *                                            was modified. Accepts 'G', 'U', or PHP date format.

	echo apply_filters( 'the_modified_time', get_the_modified_time( $format ), $format );
