I didn't want to unpublish start date or end date in jobs but i am using joomla farsi in which there is a jalali calendar.  Js jobs shows jalali calendar and it  surprised me. now after 2 weeks , I just tested and published a job in my site and suddenly found out that date shows correctly but not functioning. because every job that I publish are expired!! except those who I create from back-end.(now is 2018 but in Jalali calendar it is 1397). JS job shows it correct but all jobs that published now are expired!!!
So I decided to disable publish date and end day. But when I wanted to Unpublish date in the fields I found out I can not even unpublish dates,
I am really disappointed and desperately looking for a solution for this problem. If there is any way or any solution I am eagerly waiting for response.

Thank you in advance

the posting time and date is shows correctly even in Jalali calendar.(in back-end). But the start publish and end publish time is not correct (since 2018 to 1397 is about 621 years earlier...

old code
       $data = JHTML::_('date',strtotime($data),"Y-m-d H:i:s" );
       $data = JHTML::_('date',strtotime($data),"Y-m-d H:i:s" );
new code
       $data = date('Y-m-d H:i:s',strtotime($data) );
       $data = date('Y-m-d H:i:s',strtotime($data));


if you change your joomla admin to farsi then also change this
