If an unregistered person provides service subject to RCM to a registered person, then self invoice can be the time of supply. So time limit is not a concern here I think.
But if a registered person provides similar service to another registered person, then the time of supply would be date of payment or 61st day from issue of invoice, whichever earlier.
Thus in case of B2B supplies under RCM, if tax is not paid by the recipient within 60 days of invoice, then interest would be applicable.
