Pulling a timestamp from an XML feed with PHP but seem to be to many digits

Question

I am pulling a timestamp from a feed and it gives 12 digits (1269088723811). When I convert it, it comes out as

1901-12-13 20:45:52,

but if I put the timestamp into http://www.epochconverter.com/ it comes out as

Sat, 20 Mar 2010 12:38:43 GMT, which is the correct time.

epochconverter.com mentions that it maybe in milliseconds so I have amended the script to take care of it using

$mil = $timestamp;
$seconds = $mil / 1000;
$date = date('Y-m-d H:i:s', date($seconds));

but it still converts the date wrong, 1970-01-25 20:31:23.

What am I doing wrong?

Answer 1

This seems to be a trimmed microtime() output. The only thing you seem to be doing wrong is using date($seconds) instead of the raw $seconds. Try

$date = date('Y-m-d H:i:s', $seconds); 

Answer 2

$xml = new SimpleXMLElement('<foo><a>1269088723811</a></foo>');
echo date('Y-m-d H:i:s', (float)$xml->a / 1000);

and

$xml = new SimpleXMLElement('<foo><a>1269088723811</a></foo>');
$ts = substr($xml->a, 0, -3);
echo date('Y-m-d H:i:s', $ts);

both print 2010-03-20 07:38:43 (on my Europe/Berlin machine)
