Overtake times wrong
« on: March 11, 2007, 10:53:50 AM »
Your times are consistantly 1 hour behind ... presumably because you calculate the time to catch up and then add it to the current time rather than the time of the stanford update which is 1 hour earlier.

I also assume that you are going to put your own updates back by an hour for DST as the US went on to  DST this AM as not doing so makes your data 3 hours out of date by the time you process it.

Hello Allan,

Yes, I calculate the time to catch up and and add it to the browser local time. Did you notice the "1 hour behind" only today or before today ?

As of the last files, daily_team and daily_user_summary. txt, Stanford still didn't adopt DST. If you download this file:
http://vspx27.stanford.edu/daily_team_summary.txt

you will see the header as "Sun Mar 11 03:00:00 PST 2007" and not PDT.

That header is what drives fahstats times.

Every criticism or suggestion from the user is a gift. Even if i disagree or don't answer. Obviously if there is real intellectual work on producing it the better.

Before then. I believe the one hour discrepance come from the fact that the data the update is based on is timed one hour before your update. That is to say the latest update (as I write this) was timed at 12:00 GMT and that was based on the file timed at 03:00 PST, but 03:00 PST is only 11:00 GMT hence tie one hour discrepancy. I know you know this because at the top of the page it says that the update is timed then (and so is the "catchup" tome for yourself).

BTW Although I like the EOCs layout I find that your use of local time makes yours (amongst other things) more useful.

As your signature says England I suppose your system time is set to GMT. Do you have DST there? Is there a chance your system is in DST? What does exactly it shows as the time? Like in this page it shows "Rubberband at 8:00 UTC-3". To capture local time a javaScript script is used and it is dependent on the system time settings.

I think there is something wrong. The time at the top of the page (is it what you mean by "timed"?) should be 11:00 UTC. Since it shows correctly for me (8:00 UTC -3) I can only guess the javaScript script has a bug or your system time is misconfigured. I don't use Windows but I know it used to have some quirks.

I think you know but just to be sure: The update finishes at about one hour after the file header time just by coincidence. The file is available at about 39 minutes after the file header time and the rest of the time is processing time. BTW I will upgrade the server memory in the next days and I hope that will shave a few minutes from processing time and make some queries a bit faster.

I know you got something but I can't figure out what is it. Point me to the page where you see it or better, send me a screen shot to admin at fahstats dot com

I know this is nit picking but ... the catchup time for Google still shows the 1 hour discrepancy ...
