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

With Steffen Thorsen's information in hand, here's a revised patch to the northamerica file (relative to tzdata2008a.tar.gz).

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

FW: Cuban time
by Olson, Arthur David (NIH/NCI) [E] March 10, 2008

March 10, 2008

I'm forwarding this message from Jesper Norgaard Welen, who is on the time zone mailing list, for the reason given below. --ado -----Original Message----- From: Jesper Norgaard Welen [mailto:support@worldtimeexplorer.com] Sent: Monday, March 10, 2008 6:14 To: Olson, Arthur David (NIH/NCI) [E] Subject: Cuban time Hi Arthur Unfortunately I have no authoritative information on the expected change in DST for Cuba of March 30, 2008. I checked a few internet radios in Cuba as yourself, and both gave the time in Spanish as being without DST. Also these web pages show the time of Cuba without DST: http://www.cubasi.cu/ http://www.cubavision.cubaweb.cu/portada.asp In my mind there is no doubt that Cuba *stayed* on standard time this Sunday. What will happen March 30 is another matter. Perhaps nothing. Unfortunately I have no means to send this to the tz emailing list because I don't have access to my home email right now. Please forward if you can. Regards, - Jesper Nørgaard Welen Subj: Cuban time Date: Sun, 09 Mar 2008 21:58:34 -0400 From: "Olson, Arthur David (NIH/NCI) [E]" <olsona(a)dc37a.nci.nih.gov> ---------------------------------------------------------------- I'm in Maryland which is now observing United States Eastern Daylight Time. At 9:44 local time I used RealPlayer to listen to http://media.enet.cu/radioreloj, a Cuban information station, and heard the time announced as "ocho cuarenta y cuatro" ("eight forty-four"), indicating that Cuba is still on standard time. If I use Internet Explorer to view http://www.radioreloj.cu, scroll to the bottom of the page, and wait for the animated reloj (watch) to appear in the lower-right-hand corner, it shows 9:44--what we'd expect with the current time zone database stuff. Does anyone have an official reference for the March 30, 2008 Cuban DST start date we've seen on the mailing list? --ado
