Depending on how dnsmasq is compiled, that field may hold the _time_ the
lease expires, in seconds since January 1st 1970. It's clearly not that,
since the number would be much bigger, but if your system clock is not
set, that might explain things. Could you post the results of running
the command

dnsmasq -v

which will tell us which time mode dnsmasq is in, and make things clearer.
