Automatically sets custom date and time when editing posts.
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.
