Hi!
I’m working on OJS 3.0.2 and with thema “Manuscript”.
I’ve made some modifications to an article (I’ve added the XML format) and have rescheduled the posting date to show the original date. 
But this problem appears:
1.- The date of publication of the article (2016/12/29) is not the same in the “index” page as the “page view” (2017/02/28).
View date in “page index”: https://ojstest.com/recaf/index.php/RCAF/index 
View date in “page view”: https://ojstest.com/recaf/index.php/RCAF/article/view/42 
I would be very grateful for any help.
Hi @David_Alarcon_davidy,
Just checking a hypothesis – did you edit the date formats in config.inc.php
from the defaults?

Hi! @asmecher
Thank you very much for responding so soon!
I have not edited the “date formats” in file config.inc.php (I just modified the basics necessary to be able to update) … you can see here my file: 
If the problem is not there (config.inc.php)?
Where else could I find an answer?
Thank you very much for the help!
@David_Alarcon_davidy
When you go to that article production tab in backend, then click on he button “Schedule For Publication”, what is the published date there?
Best,
Bozana
