I want to be able to set the default time in the options for a Scheduled Post to be a specific time of the day, as opposed to it defaulting to the current time. Is there a plugin or some code I can add/tweak to accomplish this? I was unable to find anything here or on Google to do this.
The plugin Automatic Post Date Filler suggested in the comments is a perfect solution. Even better than imagined with all the various preferences to how it dynamically sets up the defaults when you edit the scheduled time.
