Hey Sourav, if your image for January session was accepted without date and time and you still are not having trouble regarding this that you are not asked to change then you don't have to worry about it but if you still think that it may trouble you in your admission process or in any other situation then I would suggest you should correct your image.

NTA has released the link for image correction on the account page of students. Please visit the link below for doing correction as soon as possible:
