Hello webenaut,
Thanks for reaching out to us!
This can definitely be accomplished with a little bit of customization. First, you’ll need to follow our Themer’s Guide to copy the “views > month > single-event.php” to your theme to override the default display. You can then add the time for the event prior to the event title using the following snippet:
<?php echo tribe_get_start_date( $post, false, get_option( 'time_format' ) ) . ' a ' . tribe_get_end_date( $post, false, get_option( 'time_format' ) ); ?>
I’m sorry I wasn’t able to give you a direct response on the customization however I hope this was able to point you in the right direction.
Thanks!
