--Fixed! See below

Okay, the Main Page lists the co-ordinates for 31 May 2008 as:

West of -30°: 0.0374870832648067, 0.2812664767643918
East of -30°: 0.0374870832648067, 0.2812664767643918

However, the irc.peeron.com/xkcd/map/ for my graticule [1] shows co-ordinates of 0.702114 and 0.838062. What's going on? AshleyMorton 14:06, 30 May 2008 (UTC)

The data the map uses is wrong. It's using the DJIA from yesterday, I think. I just noticed that the opening values from today and yesterday were exactly the same and came here to see if anyone noticed any funny business. :) --ZorMonkey 14:15, 30 May 2008 (UTC)

Yeah, I noted this as well --80.216.129.239 14:19, 30 May 2008 (UTC)

The official reference implementation has the wrong market data for Friday May 30.

Debugging gives: Market open on 2008-05-30 = 12593.87 While finances.google has 12647.36 --80.216.129.239 14:12, 30 May 2008 (UTC)

Can we assume it's getting the Dow Jones info from a feed, and thus the feed is wrong? Djomp 15:02, 30 May 2008 (UTC)

My bet is that wherever they got their info from is correct, but it wasn't yet updated for today when the webpage hit it. --161.49.253.254 15:21, 30 May 2008 (UTC)

The biggest problem to all this is that it means the Saturday meetup locations are wrong, too. Darcy

Perhaps the peeron service should hit up Google every five minutes from, say, 09:35 to 10:00, just in case? I've also noticed that this server's time is ~6-7 minutes fast, so a 09:35 hit could have actually been executed at 09:28, before the market opened... --Tim P 15:25, 30 May 2008 (UTC)

Even better, if the first hit returns the exact same number as the previous day, keep trying until something changes or it gets to be, like, noon... --Tim P 15:46, 30 May 2008 (UTC)

Good - we've got this figured - now who can fix it? It certainly isn't me! <Feeling not geeky enough for this neighbourhood> AshleyMorton 16:15, 30 May 2008 (UTC)

I have sent a text message to Zigdon telling him about the problem. Hopefully he'll respond soon. Until he does, you're in Do-it-yourself-land :) FunkyTuba 16:40, 30 May 2008 (UTC)

It is now fixed. Zigdon also added code to the mechanism that grabs the Dow to check that it's a different number from the previous close. FunkyTuba 17:32, 30 May 2008 (UTC)

The problem appears to be fixed now. (Debugging gives: Market open on 2008-05-30 = 12647.36 and offset = 0.03748708326480674, 0.2812664767643918) - r0d3n7z 17:30, 30 May 2008 (UTC)

Google was a little bit slow posting the opening price this morning. I fixed it manually, but I'll update the code to avoid these kind of problems happening again. Zigdon 20:03, 30 May 2008 (UTC)

Please post details here when you do! Document, document... --Tim P 20:06, 30 May 2008 (UTC)

This has been done - the implementation will now look for updated data between 9 and 10am EDT. If no new data is posted by 10am, it's going to assume the market is closed for the day. Zigdon 23:46, 3 June 2008 (UTC)

end of the month

When looking for hash locations through Sunday and Monday, I found the reference implementation is looking for DJI data on 2008-06-30, suggesting that months are not being handled correctly. Can someone confirm?
