Hi, It looks like the dhcp_lease_time utility is not working anymore (after I upgraded to version 2.80). I tracked it down to commit 2b38e382, in the file contrib/lease-tools/dhcp_lease_time.c (when I revert the change in this file, the utility works as expected). My guess is that the author forgot to reverse the "greater-than" symbol when multiplying both sides of the equation by -1, although I'm not sure what the intent of the change was.
