It seems to work, too.  I backed out Martin Blapp's previous + my
GET_TIME() patch, and applied your one.  I get a few compilation
warnings:

cc -O -pipe  -DCLIENT_PATH='"PATH=/sbin:/bin:/usr/sbin:/usr/bin"' -Dwarn=dhcp_warn -g -I/usr/src/sbin/dhclient/client/../../../contrib/isc-dhcp/includes -DENABLE_POLLING_MODE -DNOMINUM  -c /usr/src/contrib/isc-dhcp/client/dhclient.c

but the resulting client appears to work fine:

That looks reasonable.
