jquery - PHP strtotime not being executed at all within Joomla Component -

i building custom component within joomla takes values input input form , wraps them in order sent off in soap request. 1 of input form elements date (date of birth, or it's name in form "dob") needs converted valid date format soap api accept.

i having strange issue within function accepts , prepares these form elements sent whereas php function strtotime doesn't seem working @ when attempt change date format valid format soap api handle.

here relevant function code deals time formatting post element dob:

$postvar['dob'] = date("y-d-m g-i-s", strtotime($_post['dob'])); die(print_r($postvar['dob'])); 

when die , print variable shown above see result is, strtotime ignored , doesn't die.

the form uses jquery datepicker date form element , here variable output $_post['dob'] looks when recieved function.

can see why strtotime function not having effect here , being ignored? thanks

edit: add here jquery datepicker code if of help.

jquery("#dob").datepicker({dateformat:'dd/mm/yy', changemonth: true,    stepmonths: 12, showanim:"slidedown" }); 

in joomla!, never touch of superglobals directly. also, check results get, if may reflect error condition.

$input          = jfactory::getapplication()->input; $dob            = $input->get('dob', null, 'string'); $postvar['dob'] = 'invalid'; if (!is_null($dob)) {     $dob = strtotime($dob);     if ($dob > 0) {         $postvar['dob'] = date("y-d-m g-i-s", $dob);     } }
