zdump loop problem

[Olson, Arthur David (NIH/NCI) [E]]

So...in the real world, does changing the zic.c lines reading...
			if (t >= cuthitime)
				break;
			newt = t + SECSPERHOUR * 12;
			if (newt >= cuthitime)
				break;
...to read...
			if (t >= cuthitime || t >= cuthitime -
SECSPERHOUR * 12)
				break;
			newt = t + SECSPERHOUR * 12;
...result in working code? I'd particularly appreciate feedback from
Andreas Radke or other ArchLinux users.
