This plugin overrides default date and time of edited posts with dynamically calculated custom values. This is useful especially when scheduling posts; the plugin can, for example, automatically generate new post dates by incrementing the current most future post date by a specified number of days.
Calculated custom date and time will automatically replace default values after clicking the “Edit” link next to “Publish immediately” in the post editor’s Publish module.
<h4>Features</h4>
<ul>
<li>Date/time values usable as a reference: current date/time, oldest or most future post date/time; specific time of day</li>
<li>Date/time of reference can be increased or decreased by a specific number of days/minutes</li>
