article:published_time date format

Question

i save the dates via php time() format in mysql.. for example: 1407178292

how can i convert it to a datetime for schema/article:published_time on meta tags?

<meta property="article:published_time" content="??" />

all samples i saw on net are lie this:

<meta property="article:published_time" content="2013-11-12T19:57:40+00:00" />

i mean: i must convert time() format to 2013-11-12T19:57:40+00:00 etc..

and also, can/should i use published_time in NewsArticle?

could someone help me?

Answer 1

The c format option to date() is what you're looking for

 $date = date('c', 1407178292); // the timestamp is the second parameter

Answer 2

Most trivially:

 $formatted_date = date('c', time());

Presuming you're on PHP5, which added support for ISO 8601 dates using the 'c' formatter.
