ahh well im not sure about the default format from vbulletin
cause they dont follow the php standards where you include the %sign
maybe vbulletin add's it along the process of handling the date..

but if you want to acces vbulletins preset formats they can be reached via

$dateformat = $vbulletin->options['dateformat'];
$timeformat = $vbulletin->options['timeformat'];

But lucky vbulletin stores in default unix format,
which enables us to use the php standards to calculate time/date etc
down to the secound..
