10^12 was the old definition of billion in the UK also, although in the
last few decades it has become rare and 10^9 is now the norm.
https://en.wikipedia.org/wiki/Long_and_short_scales has quite a bit about
it.

Hi,
When we recompute the scaling factor during tc_windup() there is an
opportunity for arithmetic overflow/underflow when we add the NTP
adjustment into the scale:
649 scale = (u_int64_t)1 << 63;
650 scale += \
651 ((th->th_adjustment +
