Comments doesn't show time

The issue is in your template. It has only the code for the date, not the time.

How do I make it work?
How to add time code?

what theme are you using?

Themes where doesn’t work:
Brennius
Revival

as both mentioned themes are commercial themes, please contact the theme’s developers for help with your question;

genrally, the theme would need to use a callback function for the ‘wp_list_comments()’ function, where you would need to expand the code to show the time as well;

an example for a callback function see for example in the theme Twenty Eleven in functions.php

Given the little information, here is the pseudo way: find where the commenting template information is, and stick get_comment_date(), get_comment_time() where you want the date and time to appear.

I also thought about this method, so I can just edit comments.php file.

I want them to appear at the same place where it shows months and day, but how do I find where to place the code so I don’t mess it up?

Looks like the developer would be the one to help you:
