[Typo3-dev] convert timestamp to TYPO3 datetime

[Sacha Vorbeck]

Hi,

I use the following code to generate a 10 digit unix timestamp:

// $row['beginnz'] contains a string in this format: 18.30.00.000000
$dateArrayStartZ = '';
$dateArrayStartZ = t3lib_div::intExplode('.',$row['beginnz']);
$timestampStartZ = mktime(($dateArrayStartZ[0]), ($dateArrayStartZ[1]));
echo(date("G:i", $timestampStartZ));

works.

But when I paste this timestamp into a db-field for a TYPO3 datetime 
field, a non valid value is displayed.

When I enter a time directly via the backend, TYPO3 generates a 5 digit 
timestamp.

How can I convert my 10 digit unix timestamp into the 5 digit TYPO3 
timestamp correctly?
