With this introduction in mind, I need to know how I can display the LOCAL date and time in the admin panel, instead of the default Gregorian date. Just as to get clearer about what I mean, just look at the following image.
I am going to display the post date and time in local calendar which is not Gregorian. I never intend to change what is there in the database; I just need to display it in the local calendar in the admin panel. I don't have any problems with the conversion itself. I can easily get the UnixTimeStamp using
$stamp = get_post_timestamp($post); and then convert it to local date and time. However, I have no clues how how to show it in the above picture; in other words, how can I put the result of my conversion in the "date column" in the table in the above image. I want this to apply to all of the posts being created with a certain Wordpress plugin. Any help will be welcome. Many thanks in advance.
