How to customize History Timeline
Go to Settings > History Timeline from within your admin panel.
Select an input date format. You must use this format when tagging your posts, otherwise, the post will not show up in the history timeline.
If there are multiple posts with the same tag, a random post will be shown. Only one post will be shown at a time.
Select an output date format. This is what will be displayed on the history timeline across the title of your post.
Select the order you want your history timeline to appear in. “Lowest to highest” will display the oldest post first.
Set a custom before and after christ suffix string.
You can edit the CSS of History Timeline here.
(Note: If the history timeline isn’t displaying properly, your theme’s CSS may be the problem. You can add inline CSS to the plugin’s history_timeline.php file to correct the issues.)
