Default Date Settings of a Custom Rom

I have a P780 and i am running a Custom Rom with Andorid 4.2.2. This Rom was in chinese language by default. I changed language to English in Settings under language and input. However, when i lock the screen and again switch it on, the date appears in chinese language. Here is a screenshot of the screen. Can anyone say me how to change language of the date from chinese to english
