the_modified_time( string $format = '' )

Display the time at which the post was last modified.

Parameters

$format

(string) (Optional) Either 'G', 'U', or PHP date format defaults to the value specified in the time_format option.

Default value: ''

More Information

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()) )
