If seats remain vacant after charting, those can be booked through current booking counter at certain major stations. There is no specific time for this. It can be booked after charting till departure.
You can check the availability in indianrail.gov.in

after chart preparation(3-4 hrs before departure) if there are still berths available they will be put in for current booking.you can book them only at the station in the current reservation counter.

No you cant book through irctc- you can only check availability on indianrail.gov.in under current reservation

I agree with you. I was asking manav. He told that it can be booked through irctc. Now it got deleted.
