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.
