This means that when we shift back an hour, we go from 1:59AM to 1:00AM. When we jump forwadr an hour, we go from 1:59AM to 3:00AM. There is never two 3AMs, and there can be anywhere from one to two 1:00 and 2:00AMs. /usr/src/share/zoneinfo/northamerica: # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule US 1967 max - Oct lastSun 2:00 0 S Rule US 1987 max - Apr Sun>=1 2:00 1:00 D -- Sean Kelly <smkelly@zombie.org> or <smkelly@slashnet.org> PGP KeyID: 4AC781C7 http://www.sean-kelly.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
