I always hated how drupal group the post author and the date together in one little print function. So after finding out that I could use get_defined_vars() to find all the variables that are available for me to use to further customize the theme I’m working on.

Anyhow, here are the snippets for custom date.

Custom Date For Node

print format_date($node->created, 'custom', 'M d, Y');

Custom Date For Comment

print format_date($comment->timestamp, 'custom', 'M d, Y');

ps – wrap these around the php openning and closing.
