There seems to be a huge problem with the IRCTC online booking system.While booking any opening day ticket(i.e. @8:00 hrs.) one need to 'LOGIN' at or after 8:00 hrs. in order to book a ticket else it shows the message "Booking not allowed before 8:00 a.m.".If anyone logged in before 8:00 and wished to book such a ticket , will have to logout and then re-login for the booking.
