This trick is totally for noobs.
1. Rooted s duos s7562
2. Jb system ui by funnypharmacist.
Thanks to dev for creating the app.
Download the system ui and move your old system ui and the .odex file to your extsd card.
Copy the new system ui file and paste it in /system/app/SystemUI.apk
Now set the permission to rw-r-r and just restart.
After restarting you will find your clock is in centre of status bar and have jb style notification.
Sorry for the link or the file.
You will find the file in system ui and there scroll downl and then you will find the link.
SRRY for bad english.
Press thanks if You like it.
