Until July 2024, dhclient kept track of time as seconds-since-epoch as
a time_t. This was a problem because (a) we wanted sub-second timeouts
and (b) timeouts didn't always do the right thing if the system clock
changed.
Switching to using CLOCK_MONOTONIC and struct timespec fixed those
issues but introduced a new problem: CLOCK_MONOTONIC values were being
intepreted as seconds-since-epoch and written to the dhclient.leases
file, causing confusion with DHCP leases expiring in early 1970.
Attempt to compromise between these by keeping track of both times;
any type within dhclient which is a time_t now refers to seconds past
the epoch, while any struct timespec value is a CLOCK_MONOTONIC time.
