Log Message:
Avoid signed integer overflow in ts2timo() for ts->tv_nsec
The condition would be rechecked later again after subtracting start time
and most invalid inputs rejected. In corner cases the current code can
accept certain invalid inputs that will pass checks later and behave like
valid ones (due to signed integer overflow).
