Rob (or Steve), Can you send me a definitive URL with global TZ rules so I can grep|sort|uniq to get a feel for when DST transitions occurs? I guess I thought it always was 2 am local (which implies jumps from 02h->03h and 02h->01h).
Also, possibly related, do you know of any place where DST is +/- 2 hours instead of +/- 1 hour? I ask because the still-in-development PE (phase encoded) WWVB format appears to allow for such a (non US legal) transition. I can't quite tell if it's a bug or typo or spec. /tvb ----- Original Message ----- From: "Rob Seaman" <[email protected]> To: "Tom Van Baak" <[email protected]> Cc: "Leap Second Discussion List" <[email protected]> Sent: Monday, June 01, 2015 11:27 AM Subject: Re: [LEAPSECS] Google, Amazon, now Microsoft Hi Tom, > Tony, that's my understanding too, that all DST changes always occur at 2am > local time, both times a year. > > Rob, where did you see the 1am documented? Got me. Rummaging through zoneinfo, however, many different pivot hours have been used. The point was just that there is nothing special about midnight local time.
