Most of us don’t need our post dates to be updated dynamically. But if you run a coupon site or other similar portals, you may have the need for such a feature. AutoDater for WordPress can help with that. It automatically updates your post titles with a date or time string. You can position the date anywhere.
The plugin is pretty simple to use. Once you install AutoDater, you will be able to change position, date format, and turn the script on/off from the back-end. Status report is also provided, so you can keep up with the changes. This is a free script.
