Where does NetworkManager get this from?

$ nmcli d show eth0
...
DHCP4.OPTION[22]:                       expiry = 1416136701
...

The number is the time in seconds since the epoch of the lease expiry.

Good question, I recall that monotonic time freezes while suspended.

Any solution needs to take that problem into account as well as the issue I 
see when wall clock time goes backwards.

This cannot be the first time such a time problem needed to be solved. I 
wonder what the standard pattern is for this?
