DHCPv6 is a whole different protocol, and the hacks used by those tools 
don't read-across well to it. For instance you can't use MAC addresses 
to identify leases, in fact you can't easily get a handle of a 
particular interface at all, since even a client-id, 
interface-adaptor-id pair my be associated with more than one lease, 
each of which has a different lease time.

Do you have an application in mind for this? If so it's worth thinking 
about how to do it properly (Maybe via DBUS?).

Looking that this, I did realise that the existing DHCPv4 
dhcp_lease_time tool got broken in release 2.64, and I've fixed that for 
2.67.
