I’ve added a new scheduling option in Midrub, but you can easily restore the old scheduling option from the admin panel. The new schedule option can be easily translated from the file default_user_lang.php
The new scheduling option allows you to use 12-hour or 24-hour clock format. By default is enabled the 24-hour format, but you can change it from the file application/views/user/posts.php (please don’t open the file in only Windows Code Writer). In the posts.php file you have the div with class with data-format 1, if you change to 0, you will have 12-hour clock format.
