The EXIF timestamp available from the API is already in local time, the local time where the picture was taken. What the web front-end is mistakenly doing is applying a timezone correction to this local time.
You are probably doing the same thing unknowingly, or maybe your API wrapper is. But if you get the raw EXIF timestamp from the API you can interpret it however you want. If you interpret it as UTC (for example toUTCString in javascript) then you are not applying a timezone correction. This will get you the original correct time. This is just what I've pieced together, not an official answer, YMMV. -Philip On Tue, Oct 4, 2011 at 4:54 PM, tjgupta <[email protected]> wrote: > It seems as thought Picasa Web API is passing back a different > timestamp for photos than when the photo was actually taken.
