在WordPress中将日期转换为ISO-8601

Question

I know that there are many examples of how to convert a date to ISO-8601 format with php, but how would I convert a date to 8601 for search engines but still display the standard date format (May 10, 2015) for users? I ask for the purpose of structured data markups, which require the dates to be in ISO-8601 format. I am editing a WordPress template and this is the current php script that posts the date to the page:

<?php echo date('F d, Y',strtotime($post_date[0])); ?>

So in other words, I'd still like to display the date in the standard format but also generate the date in 8601 format that only crawlers can see, within a markup such as:

<meta itemprop="datePublished" content="2015-05-15">

Thanks in advance.

You can use a built in WordPress function:

the_time( 'c' )

And display like this:

<meta itemprop="datePublished" content="<?php the_time( 'c' ); ?>">
