datetimepicker - Jquery DateTime picker restriction -

i have problem here in jquery datetime picker

 $('#eta_add').datetimepicker({     ampm: true  });

i've googled how disable future dates , works. problem how restrict date maximum time. example:

2014-03-10 23:59:59

try like:

$('#eta_add').datetimepicker({     ampm: true     hour: 23,     minute: 59,     second: 59, });

define time manually using these parameters: hour, minute , second

And
