I saw the new zone above in tzdata2010j. The last 2 rule lines produce two transitions around Apr 4, 2010.

I use zdump (a little bit modified just for formatting outputs) to detect transitions and below is the result. 2010-04-03 Sat 23:59:59-0700[DST=0] > 2010-04-04 Sun 01:00:00-0600[DST=0] 2010-04-04 Sun 01:59:59-0600[DST=0] > 2010-04-04 Sun 03:00:00-0500[DST=1] I guess the second line from the bottom would be - -7:00 Mexico M%sT 2010 Apr 4 2:00 I'm wondering if this is intended, or just a bug. -Yoshito

The second line from the bottom should indeed be... -7:00 Mexico M%sT 2010 Apr 4 2:00 ...and I plan to get it corrected in the next release. --ado -----Original Message----- From: yoshito_umaoka@us.ibm.com [mailto:yoshito_umaoka@us.ibm.com] Sent: Wednesday, June 02, 2010 12:08 To: tz@lecserver.nci.nih.gov Subject: Re: proposed time zone package changes (Bahia de Banderas; version naming) Arthur David Olson <olsona@elsie.nci.nih.gov> wrote on 05/01/2010 10:19:16 AM:
