Daylight Savings Change and SXSW
I hadn't expected the Daylight Savings Time change in 2007 to affect any of my work directly.  However, earlier this week, I found myself looking at a SXSW schedule and wondering why all the events on Sunday were starting an hour later than expected.  It ends up being a glitch because we store timestamps in the database using UTC and we only ever had to add a few hours to turn them into the local Austin times.  Well, this year, since we "spring forward" in the middle of SXSW week, on some days the local time is UTC+6, while on the rest, local time is UTC+7.  It ended up only being a small change to handle this, although I had to touch several parts of the application to get all the dates right.

I'm excited about the other changes: I've got Google Maps support working nicely, and I've added the option to download MP3 files through the web browser in addition to playing them through Pocket Tunes Deluxe.  We've got the graphics all updated for this year's look and feel, and I think I'll be sending a build to SXSW in the morning for their approval.

Is there anything in the schedule and/or the app to remind users that the daylight savings change is happening? After a few brews at a few shows the night before, I could imagine the extra help would be appreciated.

No, there's no notice about DST... however, I'll put a link to the Palm DST change update site on the download page so people don't forget to update their devices.

The leap forward happens on the Sunday morning of Film/Interactive, not during Music. That's not to say that people won't be beer-blitzed.

Coincidentally, today was the first day that I realized the time change might affect my code, as I was experimenting with adding hCalendar tags to selected portions of sxsw.com in order to appease the microformats nazis (wink wink, Tantek ;-) at technorati.com.

And, of course, congrats for getting the app ready for another year.
