We discard up to one second's worth of accounting bytes when time moves backward?
In main.c's second_elapsed_callback() we do:
if (accounting_is_enabled(options) && seconds_elapsed >= 0) accounting_add_bytes(bytes_read, bytes_written, seconds_elapsed);
So that means if our clock goes backwards, we don't count whatever bytes we spent towards whether we should hibernate.
Is that actually wise? Does this situation happen often enough to matter? This bandwidth accounting stuff is messy.
