@$NetBSD: patch-src_tracker_TrackerStartup.cpp,v 1.2 2015/06/25 06:01:01 dholland Exp $

Taking the absolute value of the difference of two values doesn't work
if the difference is unsigned. Do something else semi-reasonable
instead for the case when the clock goes backwards.

1.1
log
@Taking the absolute value of the difference of two things doesn't work
if the difference is unsigned. Do something else instead. (It is
backup logic for the clock going backwards while fading out the splash
screen, so it's not exactly critical.) Caught by the Solaris C++
compiler, which warns if you try to pass an unsigned value to abs().
