Why is my PHP code displaying an incorrect ISO 8601 date?

Incorrect ISO 8601 Date Display using PHP

When attempting to display a datetime as an ISO 8601 formatted string, users may encounter incorrect output. Specifically, timestamps such as "17 Oct 2008" incorrectly display as "1969-12-31T18:33:28-06:00."

Misidentified Argument

The main issue lies in the structure of the provided code:

<?php echo date("c", $post[3]); ?>

Here, the second argument of the date() function is $post[3], which represents a database timestamp string. However, the date() function expects a UNIX timestamp as its second argument.

Solution: Converting Database Timestamp

To correct this, you need to convert your database timestamp into a UNIX timestamp using the strtotime() function. The corrected code becomes:

<?php echo date("c", strtotime($post[3])); ?>

By incorporating this change, the correct ISO 8601 formatted string will be generated, resolving the incorrect display issue.
