Cuban Time Zone
by Jota Jota March 13, 2008

March 13, 2008

Hi: I just want to say that Cuba ("America/Havana" time zone) is EST (Eastern Standard Time -0500) and not CST (Central Standard Time -0600) during the Standard Time. In DST Cuba is EDT (Eastern Daylight Time -0400) and not CDT (Central Daylight Time -0500) Best regards Jota ____________________________________________________________________________________ Looking for last minute shopping deals?

I'm forwarding this message from Sergio Britos, who is not on the time zone mailing list (and who has a ".py" electronic mail address). Those of you who are on the time zone mailing list, please direct replies appropriately. (The "southamerica" file shows Asuncion as having done its southern-hemisphere-winter fall-back on March 9.) --ado From: Sergio Britos (Capital Markets) [mailto:sbritos@capitalmarkets.com.py] Sent: Thursday, March 13, 2008 10:39 To: tz(a)lecserver.nci.nih.gov Subject: There have been a recent advancing of 1 hour in clock so that in Asuncion Paraguay, right now is 10:00a.m. not 9:00 am.

FW: Possible error with timezone for Saint Pierre/Miquelon?

I'm forwarding this message from David Hancock; since sending it, he has asked to be added to the time zone mailing list and has been added. --ado From: Hancock, David (dhancock) [mailto:dhancock@arinc.com] Sent: Thursday, March 13, 2008 8:05 To: tz(a)lecserver.nci.nih.gov Cc: Raymond, Bill (BRAYMOND) Subject: Possible error with timezone for Saint Pierre/Miquelon? Please see the note below from one of my colleagues, Bill Raymond. He was following up on a discrepancy in our airport local-time lookup for one of the airports our customers use. He verified that the island follows DST by calling the airport authority there. Neither of us knows the start and end dates for DST, though. One of our destination airports is LFVP - Saint Pierre/Miquelon. There is a timezone America/Miquelon but the current setting is GMT -3 with no DST. LFVP is currently is DST and is GMT -2. It looks like the Olson data has DST info for 2007 but not for 2008. I did check several sources to confirm, including making a call to Air St. Pierre at the airport to check local time. For now I set LFVP to Etc/GMT -2. Please let me know if there will be an update. We recently integrated the timezone DB into our flight-planning site and it's working out very well. We've also been using worldtimeengine.com, which is great for obtaining timezone information using latitude and longitude. Cheers! -- David Hancock | dhancock(a)arinc.com

Re: Proposed change to time zone northamerica file: deferred Cuban DST
by Arthur David Olson March 12, 2008

March 12, 2008

With Steffen Thorsen's information in hand, here's a revised patch to the northamerica file (relative to tzdata2008a.tar.gz). Absent objections or better information, I'll try to put tzdata2008b.tar.gz in place this coming Saturday morning (to--barely--beat the transition time). --ado ------- northamerica ------- *** /tmp/geta11739 Wed Mar 12 10:00:56 2008 --- /tmp/getb11739 Wed Mar 12 10:00:56 2008 *************** *** 1,4 **** ! # @(#)northamerica 8.20 # <pre> # also includes Central America and the Caribbean --- 1,4 ---- ! # @(#)northamerica 8.22 # <pre> # also includes Central America and the Caribbean *************** *** 2205,2210 **** --- 2205,2252 ---- # # http://www.worldtimezone.com/dst_news/dst_news_cuba03.html + # From Arthur David Olson (2008-03-09): + # I'm in Maryland which is now observing United States Eastern Daylight + # Time.
