javascript - Invalid Date in Fullcalendar js and Firefox, how to? -

i using php send data fullcalendar, calendar dates display invalid date or nan

see date formatting below, ideas how fix this?

php

foreach ($dates $key => $date) {     //$date->getdate() timestamp     $start = new datetime($date->getdate());     $end   = new datetime($date->getdate() + 1800);      $array[$key]['start']       = $start->format('c');     $array[$key]['end']         = $end->format('c'); } 

javascript

$calendar.fullcalendar({     header     : h,     defaultview: 'month',     slotminutes: 15,     editable   : false,     droppable  : false,     events     : {         url : '/api',         type: 'post',         data: data     } }); 

edit:

i end using:

$da = date('y-m-d h:i:s', $date->getdate()); $datetimea = new datetime($da);  $array[$key]['start'] = $datetimea->format(datetime::iso8601); 

it because date formatted incorrectly, firefox require utc format work, is:

 yyyy + '-' + mm + '-' + dd + 't' + hh + ':' + min + 'z'; 

behing yyyy year formatted @ 4 digits, mm month formatted @ 2 digits (january - 00, 0 important), dd day formatted @ 2 digits, hh hour formatted @ 2 digits , min minutes formatted @ 2 digits.

t , z constants.

so change format if want hours , minutes:

$array[$key]['start']       = $start->format('y-m-d\th:i:s\z'); $array[$key]['end']         = $end->format('y-m-d\th:i:s\z'); 

hope works. tell me if doesn't , try solve :)
