How can I remove only submitted time from node view? I only need to remove the published time from the submitted by field while viewing the node. Is it possible to do with display suite or there are other different approaches?
Step 1->create a custom date format go to "admin/config/regional/date-time" then click "Add format" link,give appropriate name, in my case i have taken name "new custom", in format string input "l,F d, Y" then save.

Step 2->In your Your_theme.theme file write the preprocess function for node:

function Your_theme_preprocess_node(&amp;$variables) {
// Getting the node creation time stamp from the node object.
  $date = $variables['node']-&gt;getCreatedTime();
// Here you can use drupal's format_date() function, or some custom PHP date formatting.
 $variables['date_custom'] = \Drupal::service('date.formatter')-
 &gt;format($date, 'Machine_name_of_created_date_format'); //In my case machine name was "new_custom"
   }


Step 3->Create a twig template of your content type like node--your-content-machine-name.html.twig 

replace the following line :
{% trans %}Submitted by {{ author_name }} on {{ date }}{% endtrans %}

with

{% trans %}Submitted by {{ author_name }} on {{ date_custom }}{% endtrans %}
